(no) fast boolean evaluation ?

It's called short circuit evaluation and as far as I know it's standard 
in most all languages. This only occurs if a conditional evaluates to 
True and the only other operators that still need to be evaluated are 
'or's or the condition evaluates to False and all the other operators 
are 'and's. The reason is those other operators will never change the 
outcome: True or'd with any number of False's will still be True and 
False and'ed to any number of Trues will still be False.

My question would be why would you *not* want this?
