=head2 Usage
This module will also provide you with some helper functions to make it
easier to use Moose types in your code.
+String type names will produce a warning, unless it's for a C<class_type> or
+C<role_type> declared within the library, or a fully qualified name like
+C<'MyTypeLibrary::Foo'>.
+
=head1 TYPE HANDLER FUNCTIONS
=head2 $type
B<Important Note>: This handler will only be exported for types that can
do type coercion. This has the advantage that a coercion to a type that
-cannot hasn't defined any coercions will lead to a compile-time error.

+The 'StrOrArrayRef' will have its stringification activated this causes the
subtype to not be created. Since the bareword type constraints are not strings
you really should not try to treat them that way. You will have to use the ','
operator instead. The author's of this package realize that all the L<Moose>
together. I realize this workaround will lead a lot of duplication in your
export declarations and will be onerous for large type libraries. Patches and
detailed test cases welcome. See the tests directory for a start on this.

+=head1 COMBINING TYPE LIBRARIES
+
+You may want to combine a set of types for your application with other type
+libraries, like L<MooseX::Types::Moose> or L<MooseX::Types::Common::String>.
+
+The L<MooseX::Types::Combine> module provides a simple API for combining a set
+of type libraries together.
