For what it’s worth, I know this problem very well, and it can take
hours to figure out whats wrong.

A linter should be able to figure this out. For example, mypy will insist that a generator has a return type of Iterable[...]. So maybe you won't have to wait for Python 4; if the mypy proposal goes forward you will be able to use type annotations to distinguish generators.
