Because perhaps the biggest mistake of the Perl-6 project was ... to call it “Perl.” It is a new language.
Yes and no. Yes - because it has a lot of features built in the core of the language itself (first being difference between method and subroutine, for example), and No - because it feel's like Perl. And it feels like Perl because you can comunicate to it in the same way you talk to Perl 5. The "spirit" of expression evalation process is there. It does the right thing from the first time you try to use it.
We don’t use Perl because of its language-goodness. ... We use it because of the vast and well-tested CPAN library.
Yes we do. CPAN is here so we don't have to reimplement stuff from scratch again and again. On the other hand, when working on a new problem I feel most comfortable expressing it in Perl. Later on, I might translate the solution to another platform - mostly for performance reasons. I like Perl because it's Perl, not because of CPAN. I use CPAN for boring problems, and to advocate it's uses to other to solve their boring problems too.
