Structural pattern matching in Python <3.10

Question

For example, to use the | operator for type annotations in <3.10, one can do from __future__ import annotations.

Is something similar possible for structural pattern matching, i.e. writing things like

match x:
    case 1:
        print("x is 1")
    case 2:
        print("x is 2")

Sorry, there is no backport. This was a deep change to the language grammar.
