It would seem that if the iterator was scoped then this wouldn't be a problem. Falling out of scope (end of the for each, or sub) would cause it to be deleted. The next call would reset it, of course this couldn't be changed now because there is surely code depending on that behaviour. I wonder if perl6 handles this better. Maybe in it hashes can return an iterator (or maybe they should if they don't).

    I really expected that localising the hash would localise the iterator. If anything were to be done about the current situation, making it so that it was would seem to be the most transparent way least likely to interfere with existing code use.

    I'd be very surprised if this wasn't fixed in P6.

    The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
