MooseX::Role::Strict − use strict ’roles’
Version 0.05
This code will fail at composition time:
{ package My::Role; use MooseX::Role::Strict; sub conflict {} } { package My::Class; use Moose; with 'My::Role'; sub conflict {} }
With an error message similar to the following:
The class My::Class has implicitly overridden the method (conflict) from role My::Role ...
To resolve this, explicitly exclude the ’conflict’ method:
{ package My::Class; use Moose; with 'My::Role' => { −excludes => [ 'conflict' ] }; sub conflict {} }
WARNING : this is ALPHA code. More features to be added later.
When using Moose::Role, a class which provides a method a role provides will silently override that method. This can cause strange, hard-to-debug errors when the role’s methods are not called. Simple use "MooseX::Role::Strict" instead of "Moose::Role" and overriding a role’s method becomes a composition-time failure. See the synopsis for a resolution.

Add "−includes" to make things easier:
with 'Some::Role' => { −includes => 'bar' };
That reverses the sense of ’−excludes’ in case you’re more interested in the interface than the implementation. I’m unsure of the syntax for auto-converting a role to a pure interface.
