Empty environment ...

[A. Sundararajan]

Hmm... I don't think there is any spec. word on preventing 
additional/extension global functions, objects and constructors.

In fact, ECMAScript specification explicitly permits extensions. Also, I 
don't know any implementation of ECMAScript that does not extend global 
environment or built-in objects.
