MooseX::Role::WithOverloading - (DEPRECATED) Roles which support overloading


version 0.17


    package MyRole;
    use MooseX::Role::WithOverloading;

    use overload
        q{""}    => 'as_string',
        fallback => 1;

    has message => (
        is       => 'rw',
        isa      => 'Str',

    sub as_string { shift->message }

    package MyClass;
    use Moose;
    use namespace::autoclean;

    with 'MyRole';

    package main;

    my $i = MyClass->new( message => 'foobar' );
    print $i; # Prints 'foobar'


MooseX::Role::WithOverloading allows you to write a Moose::Role which defines overloaded operators and allows those overload methods to be composed into the classes/roles/instances it's compiled to, where plain Moose::Roles would lose the overloading.

Starting with Moose version 2.1300, this module is no longer necessary, as the functionality is available already. In that case, use MooseX::Role::WithOverloading behaves identically to use Moose::Role.


This module is marked as deprecated, as starting with Moose version 2.1300, the functionality provided here is now built-in to Moose. You only need to use this module if you are using an older Moose (but please upgrade!).
