Advanced Perl Maven video course

This Advanced Perl training course will allow you to create modules, classes. To write Object Oriented code in the modern way, using Moose, and by using only core Perl, manually blessing references.

It is based on many years of experience teaching Perl, blended with the modern features of Perl and CPAN.

Taking this course will help you maintain existing code and it will teach you how to use modern Perl tools to write new, nice and maintainable Perl code.
