32. If PrivateBoundIdentifiers of ClassBody contains a Private Name P such that P's [[Kind]] field is either "method" or "accessor" and P's [[Brand]] field is proto,
a. Set F.[[PrivateBrand]] to proto.

a. PrivateBrandAdd(F, F).

1. Assert: P is a Private Name.
2. If O is not an object, throw a TypeError exception.

1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
a. Throw a TypeError exception.
