Changes to regex and rules & tokens make pattern matching pleasant. Grammars bring formal parsing to mainstream. The perl6 OOP way looks promising.
But on the other hand, the status page doesn't say anything meaningful - http://dev.perl.org/perl6/status.html. The wiki shows timelines only till 2007 - http://www.perlfoundation.org/perl6/index.cgi?when_will_perl_6_be_released
I can't find any information about using existing cpan modules with Perl6 or a replacement; I did stumble upon a mailing thread about perl5to6 conversion tool or something.
So, overall, what's the time-frame we are looking at when perl6 can safely be used for a new project? It looks like north of 2 years to me.
