[Bug-apl] Requests for gnu-apl-mode

[David B. Lamkins]

I have two feature requests for gnu-apl-mode:

1. Allow an escape to IBM-style function listing and editing. IOW, if
you see something like ∇fname[⎕]∇ (in the general case: ∇fname[<stuff>),
then let GNU APL handle the request directly. (At present, attempting
this in gnu-apl-mode yields `Error when parsing function definition
command' in the minibuffer.)

2. (This is unrelated to 1.) When editing a function in a gnu-apl-mode
buffer, provide a way to revert the definition without closing the edit
buffer.

Finally, a question somewhat related to 2: Is it safe to use kill-buffer
to abandon an edit?
