You're right, but that is true because there is not a boolean type, not because of the form of the check. Either form has the same problem since an int is used

You're right, but that is true because there is not a boolean type, not because of the form of the check. Either form has the same problem since an int is used in place of a true boolean (true | false | other), but I prefer the form that makes it more explicit and noticeable.
