One other area that was mentioned obliquely:  preservation of 
docstrings (and other function attributes)

I couldn't tell from your code if it attempted to publish 
function attributes:

   class Foo(object):
     @autoassign
     def __init__(self, alpha, beta, gamma):
       "Do something"
       pass

   f = Foo(3,1,4)
   print f.__init__.__doc__

I can't say I use doc-strings in __init__ methods often, and I 
suspect the autoassign is only helpful most of the time for 
__init__ methods, but if it's slated for the cookbook, 
completeness would be worth aspiring to.
