Perl::Critic::Policy::UserPerl::Critic::Policy::Modules::RequirePerlVersion(3)NAMEPerl::Critic::Policy::Modules::RequirePerlVersion - Require a "use
5.006;" or similar.
AFFILIATION
This policy is part of Perl::Critic::More, a bleeding edge supplement
to Perl::Critic.
DESCRIPTION
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.
