[racket] Turning car/cdr into multi-methods

Thanks for all the replies. This is very helpful to have a google-able term
to get started. I will read up on how other people have handled these
problems. I would think that Smalltalk would run into similar issues.

Racket is nice to get started with, but eventually I will need to move this
onto a different system, so I cannot rely upon Racket's utilities. Even
though they are very nice!

Thanks!
