Perl 6 in Perl 6?

[Darren Duncan]

Something (PyPy et al) got me wondering, is it a goal in the Perl community 
before too long to have a (compiling) implementation of Perl 6 written entirely 
in Perl 6?  Meaning, that at some point the entire non-optional codebase of the 
Perl 6 compiler (not just the parser) would be written in pure Perl 6?  This 
doesn't necessarily have to produce machine language; it could be another 
language that needs compiling itself externally, but the point is that the 
entire process of producing that target language out of Perl 6 would be written 
in Perl 6.  I know STD.pm does this for the parsing portion, but I'm wondering 
about the rest.  (Maybe the all-Perl-6 version would also eventually be able to 
produce the fastest running Perl 6 programs too, because it is easiest to write 
Perl 6 analysers/optimizers/etc in, corresponding to PyPy as I understand it.)
