=head1 NAME
Type::Coercion::Union - a set of coercions to a union type constraint
=head1 STATUS
This module is 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
the child constraints of the union type constraint.
=head1 BUGS
Please report any bugs to
L<http://rt.cpan.org/Dist/Display.html?Queue=Type-Tiny>.
