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, explictly 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.
