Hi Raymond, I assume you're referring to catlee's patch? 'str' has been changed 
to 'data' in python 3.2

While porting the patch I ran into this issue, which is that isinstance(str, 
collections.Iterable) doesn't behave exactly like hasattr(str,'next')


>>> hasattr("lol", '__next__')
False
>>> isinstance("lol", collections.Iterable)
True

so using the isinstance method would actually match against strings, which iirc 
would make the program fail. I can confirm later if needed.
