PGE isn't much of a parser; it's more like a framework for bulding parsers. So, once PGE is done, to parse perl5, you'll still have to write a grammar-ish thing that includes all of the maze of twisty executions that perl currently goes through to "parse perl". The same holds for parsing perl6 only the twisty maze isn't there (or is at least much much smaller) -Scott -- Jonathan Scott Duff [EMAIL PROTECTED]
