What kind of syntax should we use to denote the module? Something like:
(module::function args)
This idea comes from Ruby, though I am not sure it necessarily plays well with the function composition operator (func1:func2). I wouldn't want to use -> or "." because of the concept collisions those would create. Could we just use something that doesn't have a mainstream meaning, like (module#function) or (module>>function)?
module::function looks good to me. Someone else suggested allowing user-defined syntax characters; this would be a good use-case. It only has to expand into (module 'function), so the implementation is basically trivial.
Why not module:function? Abuse the property that : stands for composition. A more lispy solution of (module function) might also work, and its only an extra character. Though if I were going for an Arc solution, it should probably be (bin fn) or (md fn).
