Description

For debugging purposes, it would be useful to have Clojure-oriented toString() for functions.

novate.core.processing.async/locate-destination(async.clj:231)

instead of:

novate.core.processing.async$locate_destination@2690d691

This would remove the frustration of mentally de-mangling the function name from the Java class name.

This will have a relatively insignificant change to the generated code: An implementation of the toString() method. This will add a few dozen bytes to the size of a compiled Clojure function (for the additional bytecodes, and the constant string).

Description Clojure functions do not provide a useful override of the default Java Object.toString() method.

Because of this, any time a Clojure function is printed out, it places a load on the develop to mentally reverse the necessary name mangling to get back to the namespace and function name.

I would vastly prefer better information here: the non-mangled name of the function, including namespace and, ideally, a little bit of the available meta-data: the file name and line number.

In other words, instead of {{novate.core.processing.async$locate_destination@2690d691}} something more like {{novate.core.processing.async/locate-destination(async.clj:231)}}.

Ideally, anything that is code generated as a class should implement a useful {{toString()}}. It would be nice if reified types could identify the containing namespace and function (and file/line number) as part of their default {{toString()}}.

I suspect this would need to be controlled by a compiler option as it would slightly increase the generated bytecode size, and (imperceptably?) affect compilation speed.
