It's a pity that this needs two keywords. Given that this will be fairly rare, a little more cumbersome syntax like yield in { … yield … } should be tolerable.

Or, if you go for postfix yield { … expr.yield … }.

Functions have no ambuiguty yield fn … { … expr.yield … }.

actually, i expect it to be relatively common, e.g. in python generators are pretty commonly used, I expect Rust to be somewhat similar
