And while the thought is in my head, I think block statements should be viewed less as a tweaked version of a 'for' loop and more as an extension to generators that happens to be very handy for resource management (while allowing iterators to come over and play on the new swing set as well). I think if you take that view then the argument that they are too similar to 'for' loops loses some luster (although I doubt Nick is going to be buy this =) .
I'm surprisingly close to agreeing with you, actually. I've worked out that it isn't the looping that I object to, it's the inability to get out of the loop without exhausting the entire iterator.
'break' isn't' enough for you as laid out by the proposal? The raising of StopIteration, which is what 'break' does according to the standard, should be enough to stop the loop without exhausting things. Same way you stop a 'for' loop from executing entirely. -Brett
