RFC: apropos for functions/classes

[rjmacready]

As an opendylan beginner, I often struggle to find the types or functions that I need; I've been resorting to google and the dylan references on the main site, but I feel that this could be improved. For instance, I can have a number of dylan foundry libraries as dependencies of a project of mine, and those don't feature at the official documentation (yet?).

My proposal was to make something that would enable searching the entire "registry base" (by "registry base" I mean all projects that can be seen by the current working registry, not just the dependencies of a project) for a function / method / class; while also giving it's module + library (so we can fix imports as we use functions / types). My initial idea was to make a search by name using regex, but I think it could be useful too to search for signature - ie, all functions that receive or return strings, all members of a class, etc etc.

The inspect command can probably help give some ideas on how to implement this sort of thing (at least in terms of finding definitions by name ... this just needs a different sort of comparison / matching criteria).
