The main motivating factor for %MY:: is so that 'use Foo' allows Foo
to modify the lexical scope of its invoker, as opposed to Perl 5 where
it has to modify the whole package to import symbols.
Clearly this is a Good Thing.
As to whether other uses of %MY:: are Good Things, see previous discussions
ad nauseum on -internals and -language.
