Surely anyone who does C<< my Array @foo >>, or C<< my Scalar $foo >>
will be using it, albeit indirectly.
Of course, but without the brain-twisting effect of the
repeated classname.

Syntax error, I'd expect. Though the desired effect could probably be achieved
with the C meta-property:

I think we could do it at runtime too. You could conceivably use
runtime resolution to, for example, choose from between several
different caching behaviors to be passed to a complex routine:
