audreyt is considering using Pugs::Compiler::Rule as an alternate Rules library for Pugs, in addition to PGE.
audreyt and PerlJam suggested porting Rules to PCRE, which would let us bootstrap anywhere we can find PCRE (php, python, java, etc).
an alternative would be to implement P::C::R in plain Perl6, which is straightforward (and mostly done - see http://svn.openfoundry.org/pugs/v6/v6.pm/lib/Pugs/Grammar/P6P6Rule.pm),
or even, to port P::C::R to C (libp6re would require that the callback handlers be rewritten in C instead of Hs/P6/P5).
