Perl::Critic::Policy::Modules::PerlMinimumVersion - Enforce backward compatible code.


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. This policy allows you to specify a mandatory compatibility version for your code.

For example, if you add the following to your .perlcriticrc file:

  version = 5.005

then any code that employs our will fail this policy, for example. By default, this policy enforces the current Perl version, which is a pretty weak statement.

This policy relies on Perl::MinimumVersion to do the heavy lifting. If that module is not installed, then this policy always passes.
