Python async generator protocol edge case

Just discovered a counter-intuitive Python typing edge case: When defining a Protocol for async generators, you must either drop the `async` keyword from the interface signature or include a dummy `yield` expression. Otherwise, the type checker treats it as a Coroutine return type, breaking compatibility with async generator implementations. #Python #Programming #SoftwareDevelopment #Coding #Tech
