I hope that aside didn't detract from my primary message -- that Perl 5 just works entirely too well from a user's point of view and from a CPAN author's point of view, and that's going to cause the no news (which happens to be good news) effect you've noticed. As far as what I consider 'cleaned up', I don't have enough knowledge of the domain to identify the ways core could be simplified to be comprehensible by a mere mortal as myself. I'm confused by the overloaded meanings pads put on fields in SVs and AVs and find myself thinking maybe I'd understand better if SVs were somehow subclassed for the purpose. Temps are hard to keep straight as far as how they should work, and the code seems to agree with that. pp_ctl.c seems to be littered with special cases about how a block is exited in each op. I wonder if these cases couldn't all be assembled somewhere and some sort of block object had an "I'm exiting you now" method called on it. If courotines could be grafted onto the Perl 5, I'd be a very happy camper indeed, and it seems like logic being scarred around too much makes these sorts of large scare reworks even harder to do. I should have been more clear -- it isn't even so much that core *needs* to be cleaned up so much that, in my opinion, it's going to be *worth while* to do any possible cleaning on it. Pugs may eventually be rewritten into Perl 6 and if it does, it'll run on any virtual machine that Pugs has a back end for, including Perl 5. Pugs would then compile itself down to Perl 5 and be fully self-hosted on Perl 5. And I strongly suspect that people are going to want the portability, stability, and maturity of the Perl 5 backend for most applications. People's requirements will generally be to run their legacy Perl 5 as-is along side Perl 6 that Joe down the hall has taken upon himself to start writing. Perl 5 is much better equiped to do that than Parrot is. If this turns out to be the case, any refactoring work done on Perl 5 won't be wasted. Sorry if I'm repeating past discussion. Please tell me if this is the case.
