Perl-6.0.0-STD.pm grammar

Feb 2007: Larry releases draft of "standard grammar"

• src/perl6/Perl-6.0.0-STD.pm in Pugs repository
• STD.pm for short

More complete specification (46 printed pages)

Uses proto regexes and other odd constructs

• Plan:
• Converge/migrate existing grammar to STD.pm
• Rewrite PIR-based parsing elements (e.g., quoting) to closely follow STD.pm spec
