It's not now.. but if None where to really represent the concept None, 
as in not bound to anything, it would evaluate to nothing.

Given the statement:

a = None

And the following are all true:

  a == None
(a) == (None)
(a) == ()
(None) == ()

Then this "conceptual" comparison should also be true:

if (None):  ==  if ():
if (): == if:


Comparing if's like that wouldn't be a valid code of course, but it 
demonstrates the consistency in which the comparison is made.

I think. ;-)

Of course this is all hypothetical anyways, so it could be what ever we 
decide makes the most since, include not changing anything.

Cheers,
Ron
