First off, nice RFC. :-) I've liked this for a while now but haven't
commented on it.

Though you don't say so (or maybe I missed it), I'm assuming that $!
will be a polymorphic object, meaning that:

   die "Badness: $!"     # $!->STRING, same as Perl 5

Still works? I like the other extensions as well.

Finally, I'd vote for $! 1000 times over $@; I've always hated $@
because of its direct conflict with sh's $@, which is a completely
different beast altogether.
