Python doesn't support private anything. Although mxProxy may help in this
case. http://www.lemburg.com/python/
Another goofy approach might be:
Untested:
import new
def __unreg(self):
"""
Do some unregistering here
"""
class Reg:
def register1(self)
""" could have returned a lambda also """
return new.instancemethod(__unreg,self,Reg)
