We seem to be, once again, rehashing about this. For example, I proposed this in 2017, which was not the first time:
https://mail.python.org/archives/list/python-id...@python.org/thread/GFZFJAI4WGFYFFVQTF7DORHMY7F45XZZ/ (Gary's suggestion, and (counter) counter points to it are in the linked discussion) Would it maybe be time for someone to write a PEP for this (if they can be found), so it can then be rejected (or not)? I think there is no bikeshedding to be done on the idea, though in terms of parsing there might be (though as I mentioned in that thread, there should be no difference to generator expression parsing).
