import modules at runtime

You could also play with changing the instance's class or bases
attributes, e.g.:

>>> class T1:
	def __repr__(self):
		return "T1"
	
>>> class P1:
	def __repr__(self):
		return "P1"
	
>>> a = P1()
>>> a
P1
>>> a.__class__ = T1
>>> a
T1

--- or try things like:

>>> class T3:
	def __str__(self):
		return "T3"

>>> a.__class__.__bases__=(T3,)
>>> a
T1
>>> print a
T3
