The syntax strikes me as a little clunky, but I do like the idea. Coming from Python I've used generators a lot (which in my obviously biased opinion is a clearer name that "iterator" here) so recognise the value in having something like that in the language.
probably they gonna end up with its own generic type at the stdlib
