description: When getting the value of o[p], ToObject(o) precedes ToPropertyKey(p).
info: |
13.3.3 EvaluatePropertyAccessWithExpressionKey ( baseValue, expression, strict )
1. Let _propertyNameReference_ be ? Evaluation of _expression_.
2. Let _propertyNameValue_ be ? GetValue(_propertyNameReference_).
...
4. Return the Reference Record { [[Base]]: _baseValue_, [[ReferencedName]]: _propertyNameValue_, [[Strict]]: _strict_, [[ThisValue]]: ~empty~ }.
6.2.5.5 GetValue ( V )
1. If V is not a Reference Record, return V.
...
3. If IsPropertyReference(V) is true, then
a. Let baseObj be ? ToObject(V.[[Base]]).
...
c. If V.[[ReferencedName]] is neither a String nor a Symbol, then
i. Let referencedName be ? ToPropertyKey(V.[[ReferencedName]]).
