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?

No change in particular really pisses me off, but there are tons of stupid shit changed. Like now you're not supposed to use parenthesis for if/while/for. You have the option, but you have to add a space between the if and parenthesis otherwise it's a sub call. Really?
if(1) { print "fuck perl 6\n"; } #INVALID PERL 6 CODE

Eval has been changed to try to become closer to sepples or some shit. In general it likes more like pseudo code. Why is say encouraged instead of print now? There's tons of other stupid shit but I can't be bothered to list them.
