Before this we attempted to hack around this by only overriding has_binding. However this did not cover all cases, for example when assigning to variables before their declaration it didn't throw. By using the new find_binding_and_index virtual method we can just pretend the indirect bindings are real. Since indirect binding do come from a normal environment we need to ensure you cannot modify the binding and that properties like mutable are false as expected by the spec for such an indirect binding.
