This module is covered by the Type-Tiny stability policy.
This package inherits from Type::Coercion; see that for most documentation. The major differences are that
add_type_coercions always throws an exception, and the
type_coercion_map is automatically populated from the child constraints of the union type constraint.
Please report any bugs to http://rt.cpan.org/Dist/Display.html?Queue=Type-Tiny.
