Hey M=C3=A1rcio!

Thanks for the suggesting "trailing comma all the things" idea.  I can
certainly get behind that idea and I think it would offer an even stronger
argument than just trailing commas on function args.

I'm curious what others think about broadening the scope of the RFC to
include all the list grammars in PHP.
