in thread A philosophical proof that, a perl6 implementation can be written only by Larry Wall
... doesn't come from the fact that it's hard to parse Perl, or that it requires a Larry Wall. It comes from the fact that a parse Perl, you may have to run Perl.
This is the only correct response I can see so far. Perl6 already has more than one parser. The problem isn't that it's hard to parse it's that it has to be executed during the parse so you can't have Vim or your syntax checker always doing the parse correctly.
