Perl 6 vs Perl 5

Can we have a serious Perl 6 vs Perl 5 thread?

I've been trying to wrap my head around what roles are trying to emulate. Just an odd sort of OO way of programming?'

What else where significant changes?

The whatever star should work like scala's underbar.
Perl6 adds three new ways of creating a closure (that i know of)

sub($lorem, %ipsum) { $lorem + %ipsum<dolor> } # same as p5
-> $lorem, %ipsum { $lorem + %ipsum<dolor> }
{ $^lorem + %^ipsum<dolor> }
* + *<dolor> # limited to operators

I'd rather have just one that looks like ruby blocks or lambdas in c# (i.e. that don't make me wanna scratch my eyes out).
