MooseX::Role::Strict(3) 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.
