I interpreted this pattern there to mean "shadow Python implementations with C implementations where available, but otherwise it's okay to use the Python implementations above". Is that right?) Dan also suggested freezing the Python implementations into the binary as a way of keeping their implementations in Python, but in builtins rather than operator. > I am pleading to remove the 2nd arg to aiter, which should simplify the > code. > Done in the latest revision of https://github.com/python/cpython/pull/23847. That does indeed simplify the patch significantly, nice.[1] All checks are passing. Yury or any other core developers, would you like to merge this now? Thanks again, everyone. --Josh, Dan, and Justin [1] The latest revision adds the following to the `aiter` docs: Unlike the :func:`iter` builtin, :func:`aiter` has no 2-argument variant. Often, this variant can be replaced with assignment expressions:: while chunk := await sock.read(CHUNK_SIZE): ... I think when I originally worked on this in 2018, PEP 572 had only just been approved. :-)
