    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",
        a. Let entry be PrivateFieldFind(P, O).
        b. If entry is empty, throw a TypeError exception.
        c. Return entry.[[PrivateFieldValue]].
      4. Perform ? PrivateBrandCheck(O, P).
      5. If P.[[Kind]] is "method",
        a. Return P.[[Value]].
      6. Else,
        a. Assert: P.[[Kind]] is "accessor".
        b. If P does not have a [[Get]] field, throw a TypeError exception.
        c. Let getter be P.[[Get]].
        d. Return ? Call(getter, O).

    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.
