Hi,

The nearest solution I can propose, is to define a new function bool() of one variable and use, say, bool(x) and bool(y) instead of your Boolean variables x and y. The point is: for a function you have possibility to define its own behaviour under exponentiation, in particular, bool(x)^2=bool(x). Best wishes, Vladimir -- Vladimir V.
