In the past there was talk about marking some functions as side-effect
free so they could be allowed in guards. User defined guards.

What I'm getting at is that perhaps one want a more generalized
'mark-up-this-function-as-a' feature.

-fundef(foobar/1, [process, {doc, "Awaits an X and returns an ellipsis."}])
foobar(X) ->
    receive
       X -> ...
    end.


My god that looked ugly. But it reuses syntax we know. The 'doc' part
is inspired by common lisp's docstrings (short-descriptions
(of-function (features))).
