which is?

(alright; for the moment, it's (a) for both:

>>> import unicode
>>> u = unicode.unicode

>>> u("foo") + u(" ") + u("bar")
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: illegal argument type for built-in operation

>>> u("foo") + " " + u("bar")
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: illegal argument type for built-in operation

>>> u(" ").join(("foo", "bar"))
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: first argument must be sequence of unicode strings

but that can of course be changed...)
