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?

Before I forget, you might want to get a hold of the book "The C Programming Language" by K & R and then look at the coding style in that book. The authors usually put a space between the if and the () in order to differentiate between function and non function calls.

It just looks like Perl 6 just took a coding convention and made this into a rule.
