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