esid: sec-privatefieldget
info: |
  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).
