There's already a proposal. See https://gist.github.com/MaggieMoss/c848cb3a581979f445d075c15629c950 and https://mail.python.org/archives/list/typing-...@python.org/thread/SWAY6V7WZLVPGYQEMHXJROT2747OXSRX/

I think this would conflict with https://bugs.python.org/issue41967, where Pablo suggests moving the annotations into the parser. Annotations would then need to be valid expressions, if I'm reading it correctly. It's probably possible to work around this, but I'm not sure what it would take.

    Hey,
    python 3.9 introduced the | operator for union types. it would be
    nice to have something like that for optional types. maybe like

    name: ? int
    or
    name: int ?

    best regards
