Usage

    # easiest is via AttributeShortcuts
    use MooseX::AttributeShortcuts 0.028;
    has foo => (
        is  => 'rw',
        isa => sub { die unless $_[0] == 5 },
    );
    # or, the hard way
    use MooseX::Meta::TypeConstraint::Mooish;
    has foo => (
        is  => 'rw',
        isa => MooseX::Meta::TypeConstraint::Mooish->new(
            constraint => sub { die unless $_[0] == 5 },
        ),
    );

Version

This document describes version 0.001 of MooseX::Meta::TypeConstraint::Mooish - released March 12, 2015 as part of MooseX-Meta-TypeConstraint-Mooish.

Overview

Moose type constraints are expected to return true if the value passes the constraint, and false otherwise; Moo "constraints", on the other hand, die if validation fails.

This metaclass allows for Moo-style constraints; it will wrap them and translate their Moo into a dialect Moose understands.

Note that this is largely to enable functionality in MooseX::AttributeShortcuts; the easiest way use this metaclass is by using that package. Also, as it's not inconceivable that this functionality may be desired in other constraint metaclasses, the bulk of this metaclass' functionality is implemented as a trait.
