Summary: int object need more informative error message

Initial Comment:
When int objects encounter a NotImplementedError, 
they don't say much about what the problem is and are 
too unfriendly.

Error messages can be more verbose.

>>> reduce(int.__add__, (1, 2L))
NotImplemented

>>> reduce(int.__add__, (1L, 2))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: descriptor '__add__' requires a 'int' object but 
received a 'long'

Unfortunately, there may not be any flexibility here.  Instead 
of being just an error message, NotImplemented is a 
constant that has meaning to other layers of code.  I don't 
see a way to change this or even attach a more informative 
error message.
