Okay, that explains it. This tells me that I probably need to have PGE use separate find_lex and find_global ops instead of find_name, but for a couple of other reasons PGE should probably be doing it this way anyway. FWIW, I should note that none of the Parrot docs currently seem to describe the "builtin namespace" -- it's mentioned in the documentation for the find_name opcode but seemingly nowhere else. I didn't understand it until this last message. I'll be glad to submit a documentation patch to try to explain it -- even if only to add "XXX: we need to describe the builtin namespace" -- but I'm not quite sure where it should go. Pm P.S.: For those who are curious, the way PGE was using find_name was causing "lower" in the builtin namespace to hide the entry for the <lower> subrule in PGE::Rule. Having PGE break this out into separate find_lex and find_global calls will probably fix this (as well as some other potential scope issues). Coming soon.
