Return and set

[Paul Woolcock]

I don't know if this is better (or more "pythonic"), but it works for me on
python 2.7.

>>> class MyKlass(object):
...     def __init__(self, tok):
...         self.tok = tok
...     def gettoken(self):
...         t, self.tok = self.tok or None, None
...         return t
