Uh, isn't shared state what classes were invented for?

Py> class mygen(object):
...   def __init__(self, data):
...     self.data = data
...   def __iter__(self):
...     while 1:
...       print self.data
...       yield None
...
Py> g = mygen(0)
Py> giter = iter(g)
Py> giter.next()
0
Py> g.data = 1
Py> giter.next()
1

Cheers,
Nick.
