I like it.  Nice and general, fills a gap missing in C.  It's not C,
but it could be D (it *should* be D, not P (pee?)).

Maybe we should start a new newsgroup/mailing-list for the discussion
of such things.  It seems like a lot of the current discussion here is
about things that will never make it into ANSI C such as a power
operator, `noalias' :-) et cetera.  Sure would improve the S/N ratio
for those interested only in C.
