Hello, Python 3.10 comes with the built-in *anext()* but I think we may be missing some other equivalent built-in functions like *list* and *enumerate*. I didn't discuss the idea of creating a PEP for this but I would like to get some help with the implementation. The equivalent Python code would be *async def aenumerate(sequence, start=0): n = start async for elem in sequence: yield n, elem n += 1* The code for enumerate if here https://github.com/python/cpython/blob/2f3a87856c7033227577b9ed0c77ed7531143... The *next* function creates a tuple and return with (n, elem) *result = PyTuple_New(2);PyTuple_SET_ITEM(result, 0, next_index);PyTuple_SET_ITEM(result, 1, next_item);return result;* For the async implementation I would have to instead return an *async_generator_asend* object and that would resolve to the tuple. Calling *tp_as_async->am_anext* and getting the value doesn't seem like the solution because I should not get the result at this stage yet. I would like to have a hint on how to implement this =D
