Hi On http://natura.di.uminho.pt/~albie/parrot/ I have some documents I've been working in about PMC's: * Array PMC * Perl Array PMC * Perl Hash PMC * Perl String PMC * Writing a PMC Regarding the first four, I would appreciate PMC programmers to read them and give ideas/suggestions. In relation of the last one, check if I'm not writting stupid things :) Hugs Alberto -- Alberto Manuel B.
