MooseX::Types::CheckedUtilExports(3)			User Contributed Perl Documentation		      MooseX::Types::CheckedUtilExports(3)

NAME

       MooseX::Types::CheckedUtilExports - Wrap Moose::Util::TypeConstraints to be safer for MooseX::Types

VERSION

       version 0.35

DESCRIPTION

       Prevents errors like:

	   subtype Foo =>
	   ...

       Which should be written as:

	   subtype Foo,
	   ...

       When using MooseX::Types. Exported by that module.

       Exports checked versions of the following subs:

       "type" "subtype" "maybe_type" "duck_type" "enum" "coerce" "from" "as"

       While "class_type" and "role_type" will also register the type in the library.

       From Moose::Util::TypeConstraints. See that module for syntax.
