I think it's good that they're willing to throw away problem issues rather than to try to work around them (Working around them in later Perl 5 versions is good,
it builds stability. Keeping the crud in Perl6 is stupidity).
As far as I can tell, Perl6 is (will be) to Perl5 as C++ is to C (not in terms of functionality, but in terms of...oh, nevermind. But it's cool).
I'm looking forward to some of the byte-code translations and some of the syntax improvements. (Let's make Perl scripts shorter yet!)
