ACK.

Apparently there are at least two people who think/thought that.  AISB, 
utter nonsense being told is more the rule than the exception in this field.

[But if I consider postings elsewhere, for example in de.sci.ALL, perhaps 
this is true of any field.  It has always been easier to post nonsense than 
a sound argument.  Insofar it appears to be prudent to limit one's rebuttal 
to the key points so as not to be overwhelmed by nonsense to be refuted.  On 
the other hand, a short, to-the-point rebuttal invites even more nonsense.  
It is a difficult decision.]

That is an Editor's Draft.

You keep on quoting irrelevant sources.

Wrong, because the scope chain of that code includes more than the global 
object:
