Perl::Critic::Policy::Moose::ProhibitMultipleWiths - Require role composition
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 statement.
# ok package Foo; use Moose::Role; with qw< Bar Baz >; # not ok package Foo; use Moose::Role; with 'Bar'; with 'Baz';
This policy is part of Perl::Critic::Moose.
There is a single option,
equivalent_modules. This allows you to specify modules that should be treated the same as Moose and Moose::Role, if, say, you were doing something with Moose::Exporter. For example, if you were to have this in your .perlcriticrc file:
[Moose::ProhibitMultipleWiths] equivalent_modules = MyCompany::Moose MooseX::NewThing
then the following code would result in a violation:
package Baz; use MyCompany::Moose; with 'Bing'; with 'Bong';
