Message 306736 - Python tracker (original) (raw)

A first simple idea that comes to my mind is special-case async generators/iterators in PyObject_GetIter to say something like:

TypeError: asynchronous iterable can't be used where an iterable is expected

If it is possible to detect that an async generator is resulting from a generator expression, then we can say:

TypeError: asynchronous generator expression can't be used as an iterable
