Dan,

>What if your example were thus:
>    A AND B AND X < 10

That becomes the equivalent of 

  A and B and ( X < 10 )

Thus we are now reduced to only have AND clauses, which are short-circuit
evalutated from left to right.  So unless both A and B are true, it never has to
evaluate ( X < 10 ).

See?
