Provide a way of iterating over all defined functions

[asampal]

It would be great to have a function that allows introspection over all defined functions (possibly scoped by some of the functions' metadata) in order to be able to act on the other metadata. I can see this being helpful for tooling (e.g. a language server that might want to provide prioritized auto-completion when in a particular module, etc.).

Maybe this is already there and I missed it (since I guess something like this is being used to generate some of the documentation).

All currently-defined symbols can be accessed via the symbols command, as a dictionary (name-value).

Starting from there you can obviously get whatever you want (note: there was a tiny issue with the REPL not handling nested templates well, but it has also been fixed as per the latest PR).

For example:

This returns an array of tuples (name / description) for each of the defined built-in functions. 😉

map select keys symbols => [function?.builtin var] 'sym -> @[sym, get info.get sym 'description]

This is pretty much the same like:

map 
    select keys symbols 'sym [
        function?.builtin var sym
    ] 
    'sym [
        @[
            sym,
            get info.get sym 'description
         ]
    ]

P.S. That being said, the whole thing reminds that I have to add dictionary support for all the remaining functions in the Iterators module, so that e.g. you can select the items you want from a given dictionary and get back a dictionary. I always end up using similar things (as would be the case here), but I still haven't implemented it for Arturo... :S

@drkameleon How should we name this?

Good question. It could be functions and work in an identical way as symbols, only returning just the functions?
