Well having seen xparse I'm quite excited.  I hope this won't remain as
Latex2e* for too long, and that Latex 3 is nigh!

How will all this fit into the
programming environment of Latex3?  Will xparse and friends be rewritten
with \type_name:args.  In fact what is the status of this aspect of
Latex3?

One feature which I think would be nice is a \newargumenttype macro,
analogous to \newcolumntype of the array package.

I wait with anticipation the template packages &c.
