However if the capture was explicit and any valid target could be used as a capture variable then I could express this cleanly: |def update_point_3d(p: Point3d, pt): match pt: case (p.x=, p.y=): pass case Point2d(p.x=, p.y=): pass ... |
I like this proposal, using = to explicitly specify when capturing. I see it as a big improvement over the current PEP where dotted names are never assigned to and non-dotted names usually are. It also leads directly to an alternate proposal for the wildcard pattern: a "=" not prefaced with an lvalue. This has the benefit of having no conflict with i18n, etc.
Explicit is better than implicit, //arry/
