<@U6ZRNH0TC> if you use yield once in a method, you turn the whole method into a python generator object, so that makes some sense - but python generator objects can still `return` if you've used `yield` before, can't they?

Yes. They can still `return`. I don't understand the semantics of that tho

only a bare return, which is "end of iteration"

the python parser checks for `yield` and `return value` being mixed

It does explode, but the error message is not as informative as this thread has been :slightly_smiling_face: Thanks!
