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.

I like this syntax.
