The idea here is to have a function with which to show warnings to the user, which can be dynamically bound. Any binding should be a function of one argument, which it should print, log, or otherwise display.

Compose and return a sensible reason message for this exception.

Compose a reason message for this exception, log it (with its stacktrace), and return the reason message.

Clojure stacktraces are unreadable. We have to do better; evaluate this form in a try-catch block; return a map. If the evaluation succeeds, the map will have a key :result whose value is the result; otherwise it will have a key :error which will be bound to the most sensible error message we can construct. Additionally, log the exception

Evaluate the supplied form in a try/catch block. If the keyword param :message is supplied, the value will be used as the log message; if the keyword param :error-return is supplied, the value will be returned if an exception is caught.

Sending empty strings, or numbers as strings, to the database often isn’t helpful. Massage these params and form-params to eliminate these problems. We must take key field values out of just params, but we should take all other values out of form-params - because we need the key to load the form in the first place, but just accepting values of other params would allow spoofing.

Return a map with one key, this k as a keyword, whose value is the binding of k in map m, as read by read.

Sending empty strings, or numbers as strings, to the database often isn’t helpful. Massage these params and form-params to eliminate these problems. Date and time fields also need massaging.
