On a somewhat related note, I'd very much like the ability for two
LexInfo names to point to the same underlying register, as it would make
certain Perl6isms easier ($!foo vs $foo, for example).

Leo explained on #parrot a while ago that there's nothing
architecturally forbidding it, but the current implementation uses a 1:1
mapping for simplicity.  Is it possible to get a 1:N mapping from
registers to names?
