An excellent example of how easy it is to make confusing identifiers. I keep reading examples in style guides where someone says a declaration like const int two = 3; is bad. Well, two = 3 is obvious, but the one above isn't. What could be clearer than day d+1 being one day past day d? Yet d+1 is not d plus one. Some programmers say that the single most difficult task in progrmming is thinking of good variable names. I'm inclined to agree. -- hendrik ____________________ Racket Users list: http://lists.racket-lang.org/users
