Sure but you can't instantiate the class.

I was imagining that one would want abstract and non-abstract methods
in a single class (forcing subclasses to override the abstract ones
only). Does class/abstract support that?

Actually I don't think so. For that, you'd need to add
class/abstract

Except it should be an error when instantiating the class, not when
calling the method, right?

Everyone adds this syntax rule to OO Racket programs:
(define-syntax-rule
(define/abstract (x y ...))
(define/public (x y ...) (error 'x "abstract method needs to be
instantiated")))
Could some kind current maintainer of class.ss add this rule and
add the
proper syntax magic?
Thanks -- Matthias
