Perl Modules
I've frequently mentioned
modules and CPAN—the
large collection of Perl code—has a huge number of modules you
can use. Most are free, but do make a point of checking for copyright
restrictions and see the discussion in the Perl FAQs about copyright
issues. These days, most modules, including the bulk of the code
available on CPAN, are written in an object-oriented style.
You'll need to extend your Perl knowledge to encompass this
style, but you won't need an in-depth view of object-oriented
techniques to use most modules in your programs.

Bioperl
An important and steadily developing suite of Perl modules for
bioinformatics is the
Bioperl project, which you can find at
the web site http://www.bioperl.org. These modules give you lots of
capabilities, all ready to use.
