=head1 NAME
Type::Coercion::FromMoose - a set of coercions borrowed from Moose
=head1 STATUS
This module is considered part of Type-Tiny's internals. It is not
covered by the
L<Type-Tiny stability policy|Type::Tiny::Manual::Policies/"STABILITY">.
=head1 DESCRIPTION
This package inherits from L<Type::Coercion>; see that for most documentation.
The major differences are that C<add_type_coercions> always throws an
exception, and the C<type_coercion_map> is automatically populated from
Moose.
This is mostly for internal purposes.
=head1 BUGS
Please report any bugs to
L<http://rt.cpan.org/Dist/Display.html?Queue=Type-Tiny>.
