[racket] Type-class-like idiom in Racket?

Danny & Matthias,

I hadn't known about structure properties. I think lumping enough syntactic
sugar onto your syntax definitions, Matthais, might make it feasible to
reproduce something to provide the functionality I'm looking for.

The only thing is, how do you extend these properties to built-in types
like LIST and VECTOR? I'm guessing that you'd need to wrap them in a
user-defined type...
