Hi Gary,

I'm glad to see you are back onto M4, but I would like to emphasize
the need for a _stable_ release, with *no new feature* except the
modules.  Prototyping needs careful thought, and the proposal is not
clear to me (e.g., maybe formal arguments should have a $ in front.
Pay attention to Autoconf using `foo(bar)' something without imagining
that M4 will think this is an argument).

Therefore, it would be a good thing for M4, IMNSHO, that we make a
good 1.5 with not more than what's already in the box.

My $0.02.
