ActivePython 2.4.1 Build 247 (ActiveState Corp.) based on
Python 2.4.1 (#65, Jun 20 2005, 17:01:55) [MSC v.1310 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> class Test: pass
...
 >>> i = Test()
 >>> i+1
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: unsupported operand type(s) for +: 'instance' and 'int'
 >>> def __add__(self): return 6
...
 >>> i.__add__ = __add__
 >>> i+1
6
 >>>

Was this in reference to a specific python version?
