According to the spec. it should alert the global object:
The reference to foo resolves to a Reference to an object environment record.
When getValue is called on that reference it goes through step 5.a and calls
GetBindingValue on the env record. GetBindingValue does a [[Get]] on the
global object. [[Get]] internally retrieves an accessor property and does a
call to the [[Get]] function passing the global objet as the this value.
