     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      ...
     15      4. Perform ? PrivateBrandCheck(O, P).
     16      5. If P.[[Kind]] is "method",
     17        a. Return P.[[Value]].
     18      ...
     19 
     20    PrivateBrandCheck(O, P)
     21      1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
     22        a. Throw a TypeError exception.
