int rich comparisons

[George Sakkis]

I stumbled upon the following strangeness (python 2.6.2):
Traceback (most recent call last):n
File "<stdin>", line 1, in <module>
AttributeError: 'int' object has no attribute '__gt__'

Is this a bug ?

I don't think so. Notice that in the first example you're picking
up the __gt__ method of the *type* object, not the int object; i.e.,
the method that's executed when you do:
True

You get similar results with __call__:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'int' object has no attribute '__call__'

I believe that ints in the 2.x series still use __cmp__. In Python 3.x, __gt__
and the rest are defined.

Correct:
