Perl::Critic::Policy::Modules::RequirePerlVersion(3) User Contributed Perl Documentation Perl::Critic::Policy::Modules::RequirePerlVersion(3)

Perl::Critic::Policy::Modules::RequirePerlVersion - Require a "use 5.006;" or similar.

This policy is part of Perl::Critic::More, a bleeding edge supplement to Perl::Critic.

As Perl evolves, new desirable features get added. The best ones seem to break backward compatibility, unfortunately. As a favor to downstream developers, it's good to state explicitly which Perl version will not be able to parse your code.

For example, the "our" keyword was first appeared in a stable Perl in version 5.6.0. Therefore, if your code employs "our", then you should have a line like this near the very top of your file:

    use 5.006;

or

  use v5.6.0;

The former is preferred as the latter can trigger v-string compatibility warnings. (If someone could please explain that to me, I'd really appreciate it!)

Additionally, it's good form to state that minimum version in your Makefile.PL or Build.PL file.
