[racket] class variables in racket

[Christian Wagenknecht]

How class variables/methods (instead of instance variables/methods) can be 
implemented be means of Racket's class definition expressions? An unsatisfying 
way I found is by using a let expression enclosing the whole definition of the 
class.
