Could it be that I missunderstood you? By your kind of booleans did you 
mean the true non-integer booleans? If so, that is what the example dow 
there is for: showing why we need real bools.

And if I did missunderstand something I apologize (it's late).

Are you now saying you want real booleans that are not ints?

Scary.

My example was supposed to be an example for:
a) real bools being needed
b) int bool being bad
