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?

You have the option, but you have to add a space between the if and parenthesis otherwise it's a sub call. Really?

I can't tell if you're trolling or just plain stupid. Either way, a lot of programming languages follow this convention. The reason for this is because it's easy to tell what is and isn't a function call.
