I think the idea here is that the core language of ANTLR (the part that 
reads .g files and generates code) does not need to be ported to the 
target language. If you wanted to get antlr to create parsers that work 
on parrot, I believe you would just write a new code generator (in Java) 
that output Parrot/Perl6 code. There would also need to be a support 
library written in Parrot/Perl6 to use those generated parsers.
