Yes, all other things being equal. But will they be?
IOW: at what cost backwards compatibility?

Seems a bit of a shame to parse it and then not do anything with it,
especially if we're trying to push Perl 6 as a common language runtime
for running all sorts of bytecode-compiled languages. :)

This is what I've been arguing against. Unless I misunderstand (and it
wouldn't be the first time... :)

I don't get it.
The first and foremost duty of Perl 6 is to parse and execute Perl 6.
If it doesn't, it's not Perl 6. I will call this the Prime Directive.
I think as the first approximation the implementation of Perl 6 should
get that "simple" task right. If it doesn't, all our talk and work
