Secondly, reading from a namespace does not happen in a single clock tick, it takes quite a long time. So it's no good setting a lock bit on the namespace object itself and then immediately assuming that it's now mutable. A reading process could already have started, and be proceeding.
So what I think is, that we have a single top level function, `(::substrate:search-store key store return-key?)` (which we already sort of have in the 0.0.6 prototype, [here](https://www.journeyman.cc/post-scarcity/doc/html/intern_8c.html#a2189c0ab60e57a70adeb32aca99dbc43)). This searches a store (hashmap, namespace, association list, or hybrid association list) to find a binding for a key, and, having found that binding, then, if there is a namespace on the search path, checks whether the lock on the any namespace on the search path is set, and it it is, aborts the search and tries again; but otherwise returns either the key found (if `return-key?` is non-`nil`), or the value found otherwise.

This function implements the user-level Lisp functions `assoc`, `interned`, and `interned?`. It also implements *hashmap-in-function-position* and *keyword-in-function-position*, in so far as both of these are treated as calls to `assoc`.
