Whoops. I just had a look at the mail that Matt referenced at the top of
this thread. An anyelement2 would require a bit more than what anyenum
does, as the type-matching code that ensures that all generic args are
of the same type would have to be changed, unlike anyenum. Hope I didn't
lead you down the wrong path, Matt. OTOH, following the enum patch
should land you in roughly the right areas, and you'd still need to add
ANYELEMENT2 references in all the places that I had to add ANYENUM as well.
