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. Perform ? PrivateFieldSet(field, base, W).
PrivateFieldSet (P, O, value )
1. Assert: P is a Private Name value.
2. If O is not an object, throw a TypeError exception.
3. Let entry be PrivateFieldFind(P, O).
4. If entry is empty, throw a TypeError exception.
PrivateFieldFind (P, O)
1. Assert: P is a Private Name value.
2. Assert: O is an object with a [[PrivateFieldValues]] internal slot.
3. For each element entry in O.[[PrivateFieldValues]],
a. If entry.[[PrivateName]] is P, return entry.
