+> The Lang team has made certain decisions, such as in [PR #138458], that raise questions about the desirability of using the value namespace in this way for patterns, as described in [PR #140593]. It might be prudent to not intentionally rely on this nuance in your code.

 For example, `x @ A(..) | B(..)` will result in an error that `x` is not bound in all patterns.
 `&A(x) | B(x)` will result in a type mismatch between `x` in the different subpatterns.
