Lookups in proxy binding object for call expression.
info: |
9.1.1.2.1 HasBinding ( N )
1. Let bindingObject be envRec.[[BindingObject]].
2. Let foundBinding be ? HasProperty(bindingObject, N).
3. If foundBinding is false, return false.
...
5. Let unscopables be ? Get(bindingObject, %Symbol.unscopables%).
...
7. Return true.
9.1.1.2.6 GetBindingValue ( N, S )
1. Let bindingObject be envRec.[[BindingObject]].
2. Let value be ? HasProperty(bindingObject, N).
3. If value is false, then
a. If S is false, return undefined; otherwise throw a ReferenceError exception.
4. Return ? Get(bindingObject, N).
