I've made [[x]] in docstrings refer to other functions, like so:
(def queue ()
" Creates a queue.
See also [[enq]] [[deq]] [[qlen]] [[qlist]] [[enq-limit]]"
(list nil nil 0))
This convention is used by the /help operation I built into prompt.arc, and causes [[enq]] to link to the docstring for 'enq. I think it might be useful to support this.
