I see, your example is using generators like the first perspective I described in my response to Brendan. The generator is essentially in control and sees the 'yield' as a call to an operation for which it is prepared to handle exceptions. It's logically splicing together two call chains. Essentially using a generator as a co-routine. Ok, I buy that throw() is useful for that use case. I still think it is a different from the looping control structure case where the loop is in control rather than the iterator.
