Should we allow "PrivateIdentifier: MatchElement" under a MatchProperty?

[JLHwung]

For example,

Class C {
  #x;
 foo(obj) {
    match (obj) {
      when ({ #x: 42 }) { /* do something */ }
    }
  }
}

I think eventually we should, just like we are extending destructuring for private identifiers. I am either good with including it in this proposal or delegate it to a new one.

I think if that proposal advances, we must handle it in this proposal, and probably already need to. This proposal must match destructuring, pun intended.

Agreed. Because we've been careful so far about keeping pattern syntax very close to destructuring, we can accommodate this cleanly and easily in exactly the same way destructuring does.
