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/2f3a87856c7033227577b9ed0c77ed75311430b7/Objects/enumobject.c#L42

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
