    1. Let bindingObject be envRec.[[BindingObject]].
    2. Let foundBinding be ? HasProperty(bindingObject, N).
    3. If foundBinding is false, return false.
    ...

    ...
    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
