NAME
       Mouse::Spec - To what extent Mouse is compatible with Moose

VERSION
       This document describes Mouse version v2.5.10

SYNOPSIS
           use Mouse::Spec;

           printf "Mouse/%s is compatible with Moose/%s\n",
               Mouse::Spec->MouseVersion, Mouse::Spec->MooseVersion;

DESCRIPTION
       Mouse is a subset of Moose. This document describes to what extend
       Mouse is compatible (and incompatible) with Moose.

   Compatibility with Moose
       Sugary APIs

       The sugary APIs are highly compatible with Moose. Methods which have
       the same name as Moose's are expected to be compatible with Moose's.

       Meta object protocols

       Meta object protocols are a subset of the counterpart of Moose.  Their
       methods which have the same name as Moose's are expected to be
       compatible with Moose's. Feel free to use these methods even if they
       are not documented.

       However, there are differences between Moose's MOP and Mouse's.  For
       example, meta object protocols in Mouse have no attributes by default,
       so "$metaclass->meta->make_immutable()" will not work as you expect.
       Don not make metaclasses immutable.

       Mouse::Meta::Instance

       Meta instance mechanism is not implemented, so you cannot change the
       reftype of Mouse objects in the same way as Moose.

       Role exclusion

       Role exclusion, exclude(), is not implemented.

       -metaclass in Mouse::Exporter

       "use Mouse -metaclass => ..." are not implemented.  Use "use Mouse
       -traits => ..." instead.

       Mouse::Meta::Attribute::Native

       Native traits are not supported directly, but "MouseX::NativeTraits" is
       available on CPAN. Once you have installed it, you can use it as the
       same way in Moose. That is, native traits are automatically loaded by
       Mouse.

       See MouseX::NativeTraits for details.

   Notes about Moose::Cookbook
       Many recipes in Moose::Cookbook fit Mouse, including:

       o   Moose::Cookbook::Basics::Recipe1 - The (always classic) Point
           example

       o   Moose::Cookbook::Basics::Recipe2 - A simple BankAccount example

       o   Moose::Cookbook::Basics::Recipe3 - A lazy BinaryTree example

       o   Moose::Cookbook::Basics::Recipe4 - Subtypes, and modeling a simple
           Company class hierarchy

       o   Moose::Cookbook::Basics::Recipe5 - More subtypes, coercion in a
           Request class

       o   Moose::Cookbook::Basics::Recipe6 - The augment/inner example

       o   Moose::Cookbook::Basics::Recipe7 - Making Moose fast with immutable

       o   Moose::Cookbook::Basics::Recipe8 - Builder methods and lazy_build

       o   Moose::Cookbook::Basics::Recipe9 - Operator overloading, subtypes,
           and coercion

       o   Moose::Cookbook::Basics::Recipe10 - Using BUILDARGS and BUILD to
           hook into object construction

       o   Moose::Cookbook::Roles::Recipe1 - The Moose::Role example

       o   Moose::Cookbook::Roles::Recipe2 - Advanced Role Composition -
           method exclusion and aliasing

       o   Moose::Cookbook::Roles::Recipe3 - Applying a role to an object
           instance

       o   Moose::Cookbook::Meta::Recipe2 - A meta-attribute, attributes with
           labels

       o   Moose::Cookbook::Meta::Recipe3 - Labels implemented via attribute
           traits

       o   Moose::Cookbook::Extending::Recipe3 - Providing an alternate base
           object class
