Maybe you could use overload to achieve this. Of course, you then have
to decide what to do with the . (concatenation) operator, which is maybe
why I've never seen it done.

*If* it can be done with use overload, then I don't see why not.

If er() is an lvalue subroutine then maybe.

I don't see why it couldn't work. I also don't see what this has to do
with memoizing. Perhaps you need to explain more what you're trying to
do.
