I (former Perl5 dev) am amazed that Perl6 actually has become "production-ready", after all those years. I find it quite good, and there are many interesting new concepts.

However, some things seem to be harder. For instance, it seems that I can't use the handy =~ s/.../ string replacements anymore but have to write grammar rules. Is that true?

If the old way is still possible (without Perl5 mode) then I cannot find it in Perl6's documentation.

Apart from that -- good work!

BTW: There is only one thing which I really dislike about Perl6, and that is that "nifty logo" :-) If you want to attract professional developers you should provide a professionally looking logo.
