My main concern is what the impact on __str__ would be. It seems
"obvious" that
def str(obj, *args):
return obj.__str__(*args)
because it is ultimately int's responsibility to interpret the base
argument, not str's.
People would then come up with use cases like
class Color:
msg = {'en':['red', 'green', 'blue'], 'de':['rot','grün','blau']}
def __str__(self, language='en'):
return self.msg[language][self.value]
red = Color(0)
so you could say
print str(red, 'de')
I don't think I like this direction.

Martin
