    PrivateFieldGet (P, O)
      1. Assert: P is a Private Name.
      2. If O is not an object, throw a TypeError exception.
      3. If P.[[Kind]] is "field",
      ...
      4. Perform ? PrivateBrandCheck(O, P).
      5. If P.[[Kind]] is "method",
        a. Return P.[[Value]].
      ...

    PrivateBrandCheck(O, P)
      1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
        a. Throw a TypeError exception.
