Hi,
The example that you gave just shows how null is practically
equivalent to a non-existing variable.

How'd you fit null in that? Asking if it's filled with air?
To me, this whole conversation is pointless. I don't like aliases
(like is_null() for !isset() in this case) and I don't see the point
in being _that_ extreme about semantics. In PHP you have at least 5
ways to check that a variable is not null, introducing yet another one
is not beneficial for anything in _practice_.
Cheers,
Andrey.
