If you really want to contribute to development of Perl 6 (as opposed to development with Perl 6) for the next couple years, then fantastic -- welcome aboard!

If you just want to use Perl to get stuff done then I strongly recommend you try to use Perl 5 instead. Perl 5 is considered by many to be a great tool for bioinformatics. In contrast Perl 6 is immature in many regards including not yet being able to use most Perl 5 code including almost all of the critically important CPAN. (Update a year later: P6 can now use P5 modules on CPAN (and vice-versa). See the new and already very capable Inline::Perl5.)

This site (PerlMonks) is almost entirely about Perl 5. You're in the right place if your focus is using or developing Perl 5. In contrast, for now, Perl 6 users and developers are generally better off visiting the IRC channel #perl6 on freenode.

On #perl6 you'll find p6 experts happy to help beginners most hours of the day. Start by verifying that you have an up to date Perl 6 (#perl6ers will show you how to check) and then explain to #perl6 what you want to do with Perl 6 long term and what you are trying to do with the code you've quoted.

In case it helps I'll cover a couple things here at PerlMonks. Running your code as it is with a current Rakudo Perl 6 errors out with:

Error while compiling
Malformed initializer at ------> $aa = ;

Fixing that and recompiling gives:

invoke() not implemented in class 'X'

So, what is X? To see the gist of something use .gist:

.print for X.gist

which returns:


This is the gist of package X i.e. not what you meant. So, time to visit #perl6. :)
