GetValue(V)
...
5. If IsPropertyReference(V), then
...
b. If IsPrivateReference(V), then
i. Let env be the running execution context's PrivateNameEnvironment.
ii. Let field be ? ResolveBinding(GetReferencedName(V), env).
iii. Assert: field is a Private Name.
iv. Return ? PrivateFieldGet(field, base).
c. Return ? base.[[Get]](GetReferencedName(V), GetThisValue(V)).
PrivateFieldGet(P, O)
...
4. Perform ? PrivateBrandCheck(O, P).
5. If P.[[Kind]] is "method",
...
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).
