description: Every new evaluation of a class creates a different Private Name (private static setter)
esid: sec-runtime-semantics-evaluate-name
info: |
ClassTail : ClassHeritage { ClassBody }
...
19. Let F be constructorInfo.[[Closure]].
20. If ClassHeritage_opt is present and protoParent is not null, then set F.[[ConstructorKind]] to "derived".
21. Perform MakeConstructor(F, false, proto).
22. Perform MakeClassConstructor(F).
...
33. If PrivateBoundIdentifiers of ClassBody contains a Private Name P such that P's [[Kind]] field is either "method" or "accessor" and P's [[Brand]] is F,
a. PrivateBrandAdd(F, F).
...
PrivateBrandCheck(O, P)
1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
a. Throw a TypeError exception.
