This quibbling over $0 and $1 seems like rampant bikeshedding to me.
Given that @Larry has said that $0, $1, etc. correspond to $/[0], $/[1],
etc, if you want to keep $1 as the "first parenthesized part", then come
up with a compelling, concrete proposal for what to do with $/[0] (and
$0) keeping in mind that
@array = /(foo)(bar)(baz)/;
has to do the right thing.

IMHO, self consistency is far and away more important than consistency
with perl5.

I don't understand this. Change the fewest "key things" relative to
what? Perl5? If so, why? Is it not enough that perl5 programs will
still compile and run under perl6?

I don't know about wrong, but you're certainly entering the game a
little late.
