NAME
       Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing

DESCRIPTION
       This class represents type constraints based on an enumerated list of required methods.

INHERITANCE
       "Moose::Meta::TypeConstraint::DuckType" is a subclass of Moose::Meta::TypeConstraint.

METHODS
       Moose::Meta::TypeConstraint::DuckType->new(%options)
           This creates a new duck type constraint based on the given %options.

           It takes the same options as its parent, with several exceptions. First, it requires
           an additional option, "methods". This should be an array reference containing a list
           of required method names. Second, it automatically sets the parent to the "Object"
           type.

           Finally, it ignores any provided "constraint" option. The constraint is generated
           automatically based on the provided "methods".

       $constraint->methods
           Returns the array reference of required methods provided to the constructor.

       $constraint->create_child_type
           This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

           Note that it does not return a "Moose::Meta::TypeConstraint::DuckType" object!

BUGS
       All complex software has bugs lurking in it, and this module is no exception. If you find
