If it isn't now, I would certainly like to have a hook available through
MOP (which is, to the best of my knowledge, still unspecified).
To modify a class at runtime, use C<is also>.

I believe 'does' and 'but' operators work that way, yep. Additionally,
they're per instance. Offhand I don't even recall any way to create an
uninstantiated class with a role mixed at runtime (would my
$class_foobar = ::Foo but ::Bar do the trick?)
Probably not; but C<my ::class_foobar := Foo but Bar> might.
