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.

with qw< Bar Baz >;
# not ok

equivalent_modules = MyCompany::Moose MooseX::NewThing
then the following code would result in a violation:
