Yes, this is the solution that I eventually ended up with too. However,
the real point I was trying to raise was, wether interators should look

in so many places (e.g. tuple unpacking).

This would be a great idea. I've ended up with a sizeable bunch of small
utility functions when playing around with generators/iterators in 2.2a1.
