As seen in 54220, I discovered to my chagrin that not only do Parrot hashes have only string keys, that trying to pull the keys out as PMCs (presumably Strings) fails. Aside from the ugly failure, this design seems broken in the face of languages like Perl6 that expect to be able to use non-string hash keys. Both for direct use by Perl6 internals, and for interoperability with other languages, it seems like at least one core Parrot hash class should use PMC keys. These should be either readable directly as PMCs, or stringified if assigned to a string register. (This latter case may be optimized if the key PMC is a String, of course, but that's a different issue). This ticket can be considered in some sense the converse of 54220. That ticket asks that ordinary string keys be extractable as String PMCs, whereas this one asks that general PMC keys work, and that they stringify if extracted as ordinary strings. -'f
