+
+=head1 SYNOPSIS
+
+ use MooseX::AttributeHelpers::Collection::TypeCheck;
+
+ sub push : method {
+ my ($attr, $reader, $writer) = @_;
+ return type_check($attr, sub {@_[1,$#_]}, sub {
+ my $self = shift;
+ CORE::push(@{ $reader->($self) }, @_);
+ });
+ }
+
+=head1 DESCRIPTION
+
+This module provides one function (type_check) which is exported by default.
+It is useful when writing method providers for that involve checks on
+parameterized types.
+
+=head1 SUBROUTINES
+
+=over 4
+
+=item type_check I<attribute, get_values, method>
+
+Attribute should be the attribute you wish to do the check on, get_values a
+method that will return the values to perform the check on, and method the
+actual provided method sans type checks. If the attribute is not a
+parameterized type, the method will simply be returned unmodified. If it is,
+however, the method will be wrapped with another method that checks the types
+of the values provided by get_values to ensure that they meet the type
+requirements of the provided attribute.

+All complex software has bugs lurking in it, and this module is no
+exception. If you find a bug please either email me, or add the bug
+to cpan-RT.
