However I like the isNull method, that looks more elegant.
Really macca?
I mean the method works, and everythings ok with it, and i
also agree on that it is a tricky one, but elegant it isn't.
The method is based upon something that doesn't exist,
so it's similar to a competition, where you would count:
the faults and bads of a side, just to compare, which side
got more "minus-points", to locate the side who lost -
instead of checking who made more goods and points to be
the winner.
Anyway, no prob with the isNull method here (i do honor it too),
just thought to say that it's not elegant ;D
