=head1 NAME
Squirrel - Use Mouse, unless Moose is already loaded. (DEPRECATED)
=head1 SYNOPSIS
use Squirrel;
has goggles => (
is => "rw",
);
=head1 DEPRECATION
C<Squirrel> is deprecated. C<Any::Moose> provides the same functionality,
but better. :)
=head1 DESCRIPTION
L<Moose> and L<Squirrel> are THE BEST FRIENDS, but if L<Moose> isn't there
L<Squirrel> will hang out with L<Mouse> as well.
When your own code doesn't actually care whether or not you use L<Moose> or
L<Mouse> you can use either, and let your users decide for you.
This lets you run with minimal dependencies and have a faster startup, but if
L<Moose> is already in use you get all the benefits of using that
(transformability, introspection, more opportunities for code reuse, etc).
