decorators for methods - harder are attributes on the return type, on
the parameters, on fields, etc...).

based upon common base classes & interfaces (and __slots__).  We'd need
to update this sharing to also take into account attributes and we'd
also need to either re-generate methods or wrap the functions we
initially generated with an attributed method.  Finally to make it truly
work the new methods probably need to be declared on the actual type
created by NewTypeMaker (today they are either dynamic methods or static
methods declared in some other class).

Thanks for the reply Dino.

Any interim workaround would be great...
