Why is that needed? I.e. Why is it important for a rest argument to

Well, I don't think it is "impo

The only downside I can see to this is that if code were

Hi Andy,
thanks for your comments!

Hi Daniel!

This is a little late, but fwiw...

Not in the main emacs lisp implementation. However, cl-macs.el
provides an "flet" macro that does work on function slots; it uses
the "letf" macro which expands to include a use

Hi,
I think I got the test-suite as well as a basic macro implementation

recursive macros do not yet work, but otherwise it looks fine.
