=head1 NAME
Mouse::Spec - To what extent Mouse is compatible with Moose
=head1 VERSION
This document describes Mouse version 0.97
=head1 SYNOPSIS
use Mouse::Spec;
printf "Mouse/%s is compatible with Moose/%s\n",
Mouse::Spec->MouseVersion, Mouse::Spec->MooseVersion;
=head1 DESCRIPTION
Mouse is a subset of Moose. This document describes to what extend Mouse is
compatible (and incompatible) with Moose.
=head2 Compatibility with Moose
=head3 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.
=head3 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 C<< $metaclass->meta->make_immutable() >> will not work as you expect.
B<Don not make metaclasses immutable>.
=head3 Mouse::Meta::Instance
Meta instance mechanism is not implemented, so you cannot change the reftype
of Mouse objects in the same way as Moose.
=head3 Role exclusion
Role exclusion, C<exclude()>, is not implemented.
=head3 -metaclass in Mouse::Exporter
C<< use Mouse -metaclass => ... >> are not implemented.
Use C<< use Mouse -traits => ... >> instead.
=head3 Mouse::Meta::Attribute::Native
Native traits are not supported directly, but C<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 L<MouseX::NativeTraits> for details.
