Advanced Perl Techniques

Course Description

This course will introduce you to the latest advanced Perl techniques used by the world’s best Perl programmers. If you want to ensure that you are completely up to date on the latest Perl tools, then this is the course for you. This course discusses both the latest CPAN modules and the new features added to recent versions of the core Perl distribution. If you still write Perl as you have done for ten years then there is a lot you have missed out on and this course will quickly get you up to speed.

Because of the up to date nature of this course, it’s possible that the contents may change slightly from those described below.

The course can be run over one day in lecture style or over two days including practical exercises.
