And what happens if the separator is an instance of a subclass?

class s2(str):
    def __repr__(self):
        return "s2(%r)" % str(self)

print "foobar".partition(s2("o"))

Currently this prints:
   ('f', s2('o'), 'obar')
Should this be
   ('f', 'o', 'obar')
or not?

And what about:
   print s2("foobar").partition("x")
Currently this prints
   (s2('foobar'), '', '')
