MooseX::Role::Strict

NAME

MooseX::Role::Strict − use strict ’roles’

VERSION

Version 0.05

SYNOPSIS

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 {}
    }

DESCRIPTION

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.

ACKNOWLEDGEMENTS

TODO

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.
