Hi,

I think you might want to check out that Pycon2013 Video about Metaclass 
Prgoramming of David Beazley:
http://www.pyvideo.org/video/1716/python-3-metaprogramming

He explains how to passing attributes, such creating custom classes on 
demand and returning there signatures even when wrapped.

I think that was what you wanted to archive?
