After getting used to writing async functions, I’ve been wanting use a similar syntax to declare generator functions. Something along the lines of `iter def my_iterator() -> T` and/or `gen def my_generator() -> (T, U, V)` Obviously, for backwards compatibility, this would need to be optional or have an opt-in mechanism. Would a feature like this be at all within the realm of possibility? I’d be happy to write up a much longer discussion if so. (I found a short discussion of such a feature in the archives about 8 years ago[1]. But, since it predates both `async def` and the current type checker regime, I thought it might be worth discussing. Apologies if I missed any more recent discussions.)
