     10    PrivateFieldGet (P, O)
     11      1. Assert: P is a Private Name.
     12      2. If O is not an object, throw a TypeError exception.
     13      3. If P.[[Kind]] is "field",
     14        a. Let entry be PrivateFieldFind(P, O).
     15        b. If entry is empty, throw a TypeError exception.
     16        c. Return entry.[[PrivateFieldValue]].
     17      4. Perform ? PrivateBrandCheck(O, P).
     18      5. If P.[[Kind]] is "method",
     19        a. Return P.[[Value]].
     20      6. Else,
     21        a. Assert: P.[[Kind]] is "accessor".
     22        b. If P does not have a [[Get]] field, throw a TypeError exception.
     23        c. Let getter be P.[[Get]].
     24        d. Return ? Call(getter, O).
