Hi everyone,

Sorry if this was proposed already. I looked here
https://www.python.org/dev/peps/pep-0622/#alternatives-for-constant-value-pattern,
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.
