Perl::Critic::Policy::Moose::ProhibitMultipleWiths − Require role composition
This policy is part of Perl::Critic::Moose.
This document describes Perl::Critic::Policy::Moose::ProhibitMultipleWiths version 0.999_002.
Moose::Roles are, among other things, the answer to name conflicts plaguing multiple inheritance and mix-ins. However, to enjoy this protection, you must compose your roles together. Roles do not generate conflicts if they are consumed individually.
Pass all of your roles to a single "with" in Moose statement.
This policy has no configuration options beyond the standard ones.
Right now this assumes that you’ve only got one "package" statement in your code. It will get things wrong if you create multiple classes in a single file.
Please report any bugs or feature requests to "bug−perl−critic−moose AT rt DOT cpan DOT org", or through the web interface at <http://rt.cpan.org>.
