/**
 * A call to `reg-sub` associates a `query-id` WITH two functions.
 * 
 *   The two functions provide 'a mechanism' for creating a node
 *   in the Signal Graph. When a node of type `query-id` is needed,
 *   the two functions can be used to create it.
 * 
 *   The three arguments are:
 * 
 *  - `query-id` - typically a namespaced keyword (later used in subscribe)
 *  - optionally, an `input signals` function which returns the input data
 *    flows required by this kind of node.
 *  - a `computation function` which computes the value (output) of the
 *    node (from the input data flows)
 * 
 *   Later, during app execution, a call to `(subscribe [:sub-id 3 :blue])`,
 *   will trigger the need for a new `:sub-id` Signal Graph node (matching the
 *   query `[:sub-id 3 :blue]`). And, to create that node the two functions
 *   associated with `:sub-id` will be looked up and used.
 * 
 *   Just to be clear: calling `reg-sub` does not immediately create a node.
 *   It only registers 'a mechanism' (the two functions) by which nodes
 *   can be created later, when a node is bought into existence by the
 *   use of `subscribe` in a `View Function`.
 * 
 *   `reg-sub` arguments are:
 * 
 *  - a `query-id` (typically a namespaced keyword)
 *  - a function which returns the inputs required by this kind of node (can be supplied  in one of three ways)
 *  - a function which computes the value of this kind of node (can be supplied in one of three ways)
 * 
 *   The `computation function` is always the last argument supplied and has three ways to be called.
 *   Two of these methods are syntactic sugar to provide easier access to functional abstractions around your data.
 * 
 *   1. A function that will accept two parameters, the `input-values` and `query-vector`. This is the
 *   standard way to provide a `computation-function`
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          (fn [input-values query-vector]
 *            (:foo input-values)))
 * 
 *   2. A single sugary tuple of `:->` and a 1-arity `computation-function`:
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          :-> computation-fn)
 * 
 *    This sugary variation allows you to pass a function that will expect only one parameter,
 *    namely the `input-values` and entirely omit the `query-vector`. A typical `computation-function`
 *    expects two parameters which can cause unfortunate results when attempting to use
 *    clojure standard library functions, or other functions, in a functional manner.
 * 
 *    For example, a significant number of subscriptions exist only to get a value
 *    from the `input-values`. As shown below, this subscription will simply retrieve
 *    the value associated with the `:foo` key in our db:
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          (fn [db _]    ;; :<---- trivial boilerplate we might want to skip over
 *            (:foo db)))
 * 
 *    This is slightly more boilerplate than we might like to do,
 *    as we can use a keyword directly as a function, and we might like to do this:
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          :foo)  ;; :<---- This could be dangerous. If `:foo` is not in db, we get the `query-vector` instead of `nil`.
 * 
 *    By using `:->` our function would not contain the `query-vector`, and any
 *    missing keys would be represented as such:
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          :-> :foo)
 * 
 *    This form allows us to ignore the `query-vector` if our `computation-function`
 *    has no need for it, and be safe from any accidents. Any 1-arity function can be provided,
 *    and for more complicated use cases, `partial`, `comp`, and anonymous functions can still be used.
 * 
 *   3. A single sugary tuple of `:=>` and a multi-arity `computation-function`
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          :=> computation-fn)
 * 
 *    The `query-vector` can be broken into two components `[query-id & optional-values]`, and
 *    some subscriptions require the `optional-values` for extra work within the subscription.
 *    To use them in variation #1, we need to destructure our `computation-function` parameters
 *    in order to use them.
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          (fn [db [_ foo]]
 *            [db foo]))
 * 
 *    Again we are writing boilerplate just to reach our values, and we might prefer to
 *    have direction access through a parameter vector like `[input-values optional-values]`
 *    instead, so we might be able to use a multi-arity function directly as our `computation-function`.
 *    A rewrite of the above sub using this sugary syntax would look like this:
 * 
 *        #!clj
 *        (reg-sub
 *          :query-id
 *          :=> vector)  ;; :<---- Could also be `(fn [db foo] [db foo])`
 * 
 *   The `computation function` is expected to take two arguments:
 * 
 *  - `input-values` - the values which flow into this node (how is it wired into the graph?)
 *  - `query-vector` - the vector given to `subscribe`
 * 
 *   and it returns a computed value (which then becomes the output of the node)
 * 
 *   When `computation function` is called, the 2nd `query-vector` argument will be that
 *   vector supplied to the `subscribe`. So, if the call was `(subscribe [:sub-id 3 :blue])`,
 *   then the `query-vector` supplied to the computation function will be `[:sub-id 3 :blue]`.
 * 
 *   The argument(s) supplied to `reg-sub` between `query-id` and the `computation-function`
 *   can vary in 3 ways, but whatever is there defines the `input signals` part
 *   of `the mechanism`, specifying what input values "flow into" the
 *   `computation function` (as the 1st argument) when it is called.
 * 
 *   So, `reg-sub` can be called in one of three ways, because there are three ways
 *   to define the input signals part. But note, the 2nd method, in which a
 *   `signals function` is explicitly supplied, is the most canonical and
 *   instructive. The other two are really just sugary variations.
 * 
 *   **First variation** - no input signal function given:
 * 
 *    #!clj
 *    (reg-sub
 *      :query-id
 *      a-computation-fn)   ;; has signature:  (fn [db query-vec]  ... ret-value)
 * 
 *   In the absence of an explicit `signals function`, the node's input signal defaults to `app-db`
 *   and, as a result, the value within `app-db` (a map) is
 *   given as the 1st argument when `a-computation-fn` is called.
 * 
 * 
 *   **Second variation** - a signal function is explicitly supplied:
 * 
 *    #!clj
 *    (reg-sub
 *      :query-id
 *      signal-fn     ;; <-- here
 *      computation-fn)
 * 
 *   This is the most canonical and instructive of the three variations.
 * 
 *   When a node is created from the template, the `signal function` will be called and it
 *   is expected to return the input signal(s) as either a singleton, if there is only
 *   one, or a sequence if there are many, or a map with the signals as the values.
 * 
 *   The current values of the returned signals will be supplied as the 1st argument to
 *   the `a-computation-fn` when it is called - and subject to what this `signal-fn` returns,
 *   this value will be either a singleton, sequence or map of them (paralleling
 *   the structure returned by the `signal function`).
 * 
 *   This example `signal function` returns a 2-vector of input signals.
 * 
 *    #!clj
 *    (fn [query-vec dynamic-vec]
 *       [(subscribe [:a-sub])
 *        (subscribe [:b-sub])])
 * 
 *   The associated computation function must be written
 *   to expect a 2-vector of values for its first argument:
 * 
 *    #!clj
 *    (fn [[a b] query-vec]     ;; 1st argument is a seq of two values
 *      ....)
 * 
 *   If, on the other hand, the signal function was simpler and returned a singleton, like this:
 * 
 *    #!clj
 *    (fn [query-vec dynamic-vec]
 *      (subscribe [:a-sub]))      ;; <-- returning a singleton
 * 
 *   then the associated computation function must be written to expect a single value
 *   as the 1st argument:
 * 
 *    #!clj
 *    (fn [a query-vec]       ;; 1st argument is a single value
 *       ...)
 * 
 *   Further Note: variation #1 above, in which an `input-fn` was not supplied, like this:
 * 
 *    #!clj
 *    (reg-sub
 *      :query-id
 *      a-computation-fn)   ;; has signature:  (fn [db query-vec]  ... ret-value)
 * 
 *   is the equivalent of using this
 *   2nd variation and explicitly supplying a `signal-fn` which returns `app-db`:
 * 
 *    #!clj
 *    (reg-sub
 *      :query-id
 *      (fn [_ _]  re-frame/app-db)   ;; <--- explicit signal-fn
 *      a-computation-fn)             ;; has signature:  (fn [db query-vec]  ... ret-value)
 * 
 *   **Third variation** - syntax Sugar
 * 
 *    #!clj
 *    (reg-sub
 *      :a-b-sub
 *      :<- [:a-sub]
 *      :<- [:b-sub]
 *      (fn [[a b] query-vec]    ;; 1st argument is a seq of two values
 *        {:a a :b b}))
 * 
 *   This 3rd variation is just syntactic sugar for the 2nd.  Instead of providing an
 *   `signals-fn` you provide one or more pairs of `:<-` and a subscription vector.
 * 
 *   If you supply only one pair a singleton will be supplied to the computation function,
 *   as if you had supplied a `signal-fn` returning only a single value:
 * 
 *    #!clj
 *    (reg-sub
 *      :a-sub
 *      :<- [:a-sub]
 *      (fn [a query-vec]      ;; only one pair, so 1st argument is a single value
 *        ...))
 * 
 *   Syntactic sugar for both the `signal-fn` and `computation-fn` can be used together
 *   and the direction of arrows shows the flow of data and functions. The example from
 *   directly above is reproduced here:
 * 
 *    #!clj
 *    (reg-sub
 *      :a-b-sub
 *      :<- [:a-sub]
 *      :<- [:b-sub]
 *      :-> (partial zipmap [:a :b]))
 * 
 *   For further understanding, read the tutorials, and look at the detailed comments in
 *   /examples/todomvc/src/subs.cljs.
 * 
 *   See also: `subscribe`

 * which is typically written tersely as simple:
 * 
 *    #!clj
 *    (let [items  @(subscribe [:items])]
 *      ...)
 * 
 * 
 *   `query` is a vector of at least one element. The first element is the
 *   `query-id`, typically a namespaced keyword. The rest of the vector's
 *   elements are optional, additional values which parameterise the query
 *   performed.
 * 
 *   `dynv` is an optional 3rd argument, which is a vector of further input
 *   signals (atoms, reactions, etc), NOT values. This argument exists for
 *   historical reasons and is borderline deprecated these days.
 * 
 *   **Example Usage**:
 * 
 *    #!clj
 *    (subscribe [:items])
 *    (subscribe [:items "blue" :small])
 *    (subscribe [:items {:colour "blue"  :size :small}])
 * 
 *   Note: for any given call to `subscribe` there must have been a previous call
 *   to `reg-sub`, registering the query handler (functions) associated with
 *   `query-id`.
 * 
 *   **Hint**
 * 
 *   When used in a view function BE SURE to `deref` the returned value.
 *   In fact, to avoid any mistakes, some prefer to define:
 * 
 *    #!clj
 *    (def <sub  (comp deref re-frame.core/subscribe))
 * 
 *   And then, within their views, they call  `(<sub [:items :small])` rather
 *   than using `subscribe` directly.
 * 
 *   **De-duplication**
 * 
 *   Two, or more, concurrent subscriptions for the same query will
 *   source reactive updates from the one executing handler.
 * 
 *   See also: `reg-sub`

 *   The previous association of a `coeffect handler` with an `id` will have

 * 
 *   Within the created interceptor, this 'looked up' `coeffect handler` will

 * 
 *   This `coeffect handler` is expected to modify and return its first, `coeffects` argument.
 * 
 *   **Example of `inject-cofx` and `reg-cofx` working together**
 * 
 * 
 *   First - Early in app startup, you register a `coeffect handler` for `:datetime`:
 * 
 *    #!clj
 *    (re-frame.core/reg-cofx
 *      :datetime                        ;; usage  (inject-cofx :datetime)
 *      (fn coeffect-handler
 *        [coeffect]
 *        (assoc coeffect :now (js/Date.))))   ;; modify and return first arg
 * 
 *   Second - Later, add an interceptor to an -fx event handler, using `inject-cofx`:
 * 
 *    #!clj
 *    (re-frame.core/reg-event-fx            ;; when registering an event handler
 *      :event-id
 *      [ ... (inject-cofx :datetime) ... ]  ;; <-- create an injecting interceptor
 *      (fn event-handler
 *        [coeffect event]
 *          ;;... in here can access (:now coeffect) to obtain current datetime ...
 *        )))
 * 
 *   **Background**
 * 
 *   `coeffects` are the input resources required by an event handler
 *   to perform its job. The two most obvious ones are `db` and `event`.
 *   But sometimes an event handler might need other resources.
 * 
 *   Perhaps an event handler needs a random number or a GUID or the current
 *   datetime. Perhaps it needs access to a DataScript database connection.
 * 
 *   If an event handler directly accesses these resources, it stops being
 *   pure and, consequently, it becomes harder to test, etc. So we don't
 *   want that.
 * 
 *   Instead, the interceptor created by this function is a way to 'inject'
 *   'necessary resources' into the `:coeffects` (map) subsequently given
 *   to the event handler at call time.
 * 
 *   See also `reg-cofx`

/**
 * Returns an interceptor which will run the given function `f` in the `:after`
 *   position.
 * 
 *   `f` is called with two arguments: `db` and `event`, and is expected to
 *   return a modified `db`.
 * 
 *   Unlike the `after` interceptor which is only about side effects, `enrich`
 *   expects `f` to process and alter the given `db` coeffect in some useful way,
 *   contributing to the derived data, flowing vibe.
 * 
 *   If `f` returns `nil`, the `db` value passed to `f` will be returned instead.
 * 
 *   #### Example Use:
 * 
 *   Imagine that todomvc needed to do duplicate detection - if any two todos had
 *   the same text, then highlight their background, and report them via a warning
 *   at the bottom of the panel.
 * 
 *   Almost any user action (edit text, add new todo, remove a todo) requires a
 *   complete reassessment of duplication errors and warnings. E.g. that edit
 *   just made might have introduced a new duplicate, or removed one. Same with
 *   any todo removal. So we need to re-calculate warnings after any CRUD events
 *   associated with the todos list.
 * 
 *   Unless we are careful, we might end up coding subtly different checks
 *   for each kind of CRUD operation.  The duplicates check made after
 *   'delete todo' event might be subtly different to that done after an
 *   editing operation. Nice and efficient, but fiddly. A bug generator
 *   approach.
 * 
 *   So, instead, we create an `f` which recalculates ALL warnings from scratch
 *   every time there is ANY change. It will inspect all the todos, and
 *   reset ALL FLAGS every time (overwriting what was there previously)
 *   and fully recalculate the list of duplicates (displayed at the bottom?).
 * 
 *   <a href="https://twitter.com/nathanmarz/status/879722740776939520" target="_blank">https://twitter.com/nathanmarz/status/879722740776939520</a>
 * 
 *   By applying `f` in an `:enrich` interceptor, after every CRUD event,
 *   we keep the handlers simple and yet we ensure this important step
 *   (of getting warnings right) is not missed on any change.
 * 
 *   We can test `f` easily - it is a pure function - independently of
 *   any CRUD operation.
 * 
 *   This brings huge simplicity at the expense of some re-computation
 *   each time. This may be a very satisfactory trade-off in many cases.
 * 
 *   #### Returning nil
 * 
 *   In some cases, it's useful to apply a change to specific situations that can
 *   be determined at runtime instead of when defining the handler with an
 *   `:enrich` interceptor. Instead of forcing you to return the `db` from every
 *   non-applicable branch, you can return `nil` to use the given `db` value:
 * 
 *    #!clj
 *    (def set-last-update
 *      (core/enrich
 *        (fn [{db :db} [_ {user :user}]]
