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'), '', '')
