Slowly PGE and PGE::Perl6Regex are being updated to work with pdd15oo. Several existing tools and languages in the repo still make use of PGE::P6Regex, which uses the regex syntax that was in Synopsis 5 prior to February 2007.
Rather than spend the time converting the P6Regex to work with pdd15oo, I think it will be overall less work (and much better in the long run) if we use this as an opportunity to update older grammars to use the new Perl6Regex syntax and officially deprecate the older P6Regex. This seems especially appropriate since - the old syntax isn't really documented anywhere except in repository histories - most things using PGE are likely to need some updates anyway due to the new organization of objects and namespaces Comments and/or objections welcome.
