true, but Python handles the overflow gracefully by returning a long
instead, and in Python 3 there is no int/long dichotomy on the language
level any more. It's probably convenient to put a __format__ method on
Integer, but its implementation could be very simple:
def __format__(self,*args,**kwargs):
return int(self).__format__(*args,**kwargs)
If this leads to performance issues, one could consider writing a custom
version that accepts the python format mini-language.
