 =head1 DESCRIPTION
 
-Structured type constraints let you assign an internal pattern of type
-constraints to a 'container' constraint.  The goal is to make it easier to
-declare constraints like "ArrayRef[Int, Int, Str]" where the constraint is an
-ArrayRef of three elements and the internal constraint on the three is Int, Int
-and Str.
-
-To accomplish this, we add an attribute to the base L<Moose::Meta::TypeConstraint>
-to hold a L</signature>, which is a reference to a pattern of type constraints.
-We then override L</constraint> to check our incoming value to the attribute
-against this signature pattern.
