Aesthetically, not logically.  Neither of these makes the least bit of 
sense:

    one less than False
    one less than True

A better solution for the aesthetics would have been (it is a bit late 
now) to implement the missing unary negation operator:

   !!b;  //T->F, F->T

That operator would save even more program characters for the other int 
types, where it would be equivalent to:

   (i==0 ? 1 : 0);
