=head1 DESCRIPTION
-This module provides Moose with the ability to create type contraints
-to be are used in both attribute definitions and for method argument
-validation.
+This module provides Moose with the ability to create custom type
+contraints to be used in attribute definition.
=head2 Important Caveat
This is simply a means of creating small constraint functions which
can be used to simplify your own type-checking code.
+=head2 Slightly Less Important Caveat
+
+It is almost always a good idea to quote your type and subtype names.
+This is to prevent perl from trying to execute the call as an indirect
+object call. This issue only seems to come up when you have a subtype
+the same name as a valid class, but when the issue does arise it tends
+to be quite annoying to debug.
+
+So for instance, this:
+
+ subtype DateTime => as Object => where { $_->isa('DateTime') };
+
+will I<Just Work>, while this:
+
+ use DateTime;
+ subtype DateTime => as Object => where { $_->isa('DateTime') };
+
+will fail silently and cause many headaches. The simple way to solve
+this, as well as future proof your subtypes from classes which have
+yet to have been created yet, is to simply do this:
+
+ use DateTime;
+ subtype 'DateTime' => as 'Object' => where { $_->isa('DateTime') };
+
=head2 Default Type Constraints
This module also provides a simple hierarchy for Perl 5 types, this
Num
Int
Str
+ ClassName
Ref
ScalarRef
ArrayRef
HashRef
CodeRef
RegexpRef
+ GlobRef
+ FileHandle
Object
Role
Suggestions for improvement are welcome.
+
+B<NOTE:> The C<Undef> type constraint does not work correctly
+in every occasion, please use it sparringly.
+
+B<NOTE:> The C<ClassName> type constraint is simply a subtype
+of string which responds true to C<isa('UNIVERSAL')>. This means
+that your class B<must> be loaded for this type constraint to
+pass. I know this is not ideal for all, but it is a saner
+restriction than most others.
+
+=head2 Use with Other Constraint Modules
+
+This module should play fairly nicely with other constraint
+modules with only some slight tweaking. The C<where> clause
+in types is expected to be a C<CODE> reference which checks
+it's first argument and returns a bool. Since most constraint
+modules work in a similar way, it should be simple to adapt
+them to work with Moose.
+
+For instance, this is how you could use it with
+L<Declare::Constraints::Simple> to declare a completely new type.
+
+ type 'HashOfArrayOfObjects'
+ => IsHashRef(
+ -keys => HasLength,
+ -values => IsArrayRef( IsObject ));
+
+For more examples see the F<t/204_example_w_DCS.t> test file.
+
+Here is an example of using L<Test::Deep> and it's non-test
+related C<eq_deeply> function.
+
+ type 'ArrayOfHashOfBarsAndRandomNumbers'
+ => where {
+ eq_deeply($_,
+ array_each(subhashof({
+ bar => isa('Bar'),
+ random_number => ignore()
+ })))
+ };
+
+For a complete example see the F<t/205_example_w_TestDeep.t>
+test file.

=over 4
+=item B<create_type_constraint_union ($pipe_seperated_types | @type_constraint_names)>
+
+Given string with C<$pipe_seperated_types> or a list of C<@type_constraint_names>,
+this will return a L<Moose::Meta::TypeConstraint::Union> instance.
+
+=item B<create_parameterized_type_constraint ($type_name)>
+
+Given a C<$type_name> in the form of:
+
+ BaseType[ContainerType]
+
+this will extract the base type and container type and build an instance of
+L<Moose::Meta::TypeConstraint::Parameterized> for it.
+
+=item B<find_or_create_type_constraint ($type_name, ?$options_for_anon_type)>
+
+This will attempt to find or create a type constraint given the a C<$type_name>.
+If it cannot find it in the registry, it will see if it should be a union or
+container type an create one if appropriate, and lastly if nothing can be
+found or created that way, it will create an anon-type using the
+C<$options_for_anon_type> HASH ref to populate it.
+
=item B<find_type_constraint ($type_name)>
-This function can be used to locate a specific type constraint
-meta-object. What you do with it from there is up to you :)
+This function can be used to locate a specific type constraint
+meta-object, of the class L<Moose::Meta::TypeConstraint> or a
+derivative. What you do with it from there is up to you :)
+
+=item B<get_type_constraint_registry>
+
+Fetch the L<Moose::Meta::TypeConstraint::Registry> object which
+keeps track of all type constraints.
+
+=item B<list_all_type_constraints>
-=item B<create_type_constraint_union (@type_constraint_names)>
+This will return a list of type constraint names, you can then
+fetch them using C<find_type_constraint ($type_name)> if you
+want to.
-Given a list of C<@type_constraint_names>, this will return a
-B<Moose::Meta::TypeConstraint::Union> instance.
+=item B<list_all_builtin_type_constraints>
-=item B<export_type_contstraints_as_functions>
+This will return a list of builtin type constraints, meaning,
+those which are defined in this module. See the section
+labeled L<Default Type Constraints> for a complete list.
+
+=item B<export_type_constraints_as_functions>
This will export all the current type constraints as functions
into the caller's namespace. Right now, this is mostly used for
They will then register the type constraints in a global store
where Moose can get to them if it needs to.

constraint meta-object, which will be an instance of
L<Moose::Meta::TypeConstraint>.
+=item B<enum ($name, @values)>
+
+This will create a basic subtype for a given set of strings.
+The resulting constraint will be a subtype of C<Str> and
+will match any of the items in C<@values>. It is case sensitive.
+See the L<SYNOPSIS> for a simple example.
+
+B<NOTE:> This is not a true proper enum type, it is simple
+a convient constraint builder.
+
=item B<as>
This is just sugar for the type constraint construction syntax.
This is just sugar for the type constraint construction syntax.
+=item B<optimize_as>
+
+This can be used to define a "hand optimized" version of your
+type constraint which can be used to avoid traversing a subtype
+constraint heirarchy.
+
+B<NOTE:> You should only use this if you know what you are doing,
+all the built in types use this, so your subtypes (assuming they
+are shallow) will not likely need to use this.

=head2 Type Coercion Constructors
-Type constraints can also contain type coercions as well. In most
-cases Moose will run the type-coercion code first, followed by the
-type constraint check. This feature should be used carefully as it
-is very powerful and could easily take off a limb if you are not
-careful.
