I was just reading about topics in Perl 6, very interesting article, at perl.com and it mentions string concatenation being done with "_=" instead of ".=" -- what's that all about?

And in a teach-a-man-to-fish sort of way, where can I read about changes I'd need to know about right away if I were to use Perl 6, not the more abstract topics. Could I still use ".=" for instance?
