I'm playing around with the object-oriented subset of Racket, and have a couple of questions.
Ideally, I'd like to equip a class with a field that is visible only to it and its subclasses. As far as I can tell, though, this isn't possible. It seems that I have to make a choice between a completely private field visible only to the class (by just using "define") or making a completely public field (by using "field"). Correct? Now, let's say I make the field public. In the subclass, how do I change the default value of field? For example, in the superclass, I might have (field [a 300]) but in the subclass, I want to do something like (inherit-field [a 200]) However, as far as I can tell, the syntax doesn't support anything other than (inherit-field a) Thanks, Mark
