-// NOTE: The multiplication operation could work in this case because each
-// expression is evaluated as a 1 or 0 (true or false), and a multiplication
-// between expressions can have the value 1 only if all the expressions are
-// true. However, the order of multiplication is not guaranteed to be sequenced
-// as with logical operations. So, this is could cause serious problems
-// depending on how the compiler deals with multiplication.
