Fair point :)

Same here - I'm just starting to think that the alternative is worse, because 
it leaves open the nonsensical possibility of writing a __with__ method as a 
generator *without* applying the contextmanager decorator, and that would just 
be bizarre - if you want to get an iterable, why aren't you writing an 
__iter__ method instead?

Cheers,
Nick.
