[Python-Dev] PEP 622: Arrow for capture patterns

Hi everyone, Sorry if this was proposed already. I looked here https://www.python.org/dev/peps/pep-0622/#alternatives-for-constant-value-pa..., search for "idea to make lookup semantics the default". I saw that a few symbols like $ and ? were proposed, and I thought that maybe the annotation syntax -> could indicate a capture expression, like so: case x: match Point(-> a, -> b): ... match -> whatever: do_something(whatever) I like the arrow because it's easy to imagine the value "entering" the variable. What do you think? Thanks, Ram.
