[racket-dev] class implementation and make-primitive-class

For purposes of your course project, couldn't you make your own 
class-instance object system, atop structs or hashes, that gives you 
whatever dynamic programming features you want?  It's very-very easy to 
do a basic one (with single inheritance and single dispatch), until you 
get into speed optimizations.

Or, if Swindle has a MOP, you could use that.
