Description

       This class is useful for performing mixin inheritance like merging of typemaps, by shadowing an ordered
       list.

       This is used internally to overlay the user typemap on top of the KiokuDB::TypeMap::Default instance
       provided by the backend.

       This differs from using "includes" in KiokuDB::TypeMap because that inclusion is computed symmetrically,
       like roles.

                   typemaps => [
                       $first,
                       $second,
