[racket] Declarative Prototype Object Extension - looking for feedback

I agree with Ryan and would add that you could do more with some of
Racket's other features. For instance, in my prototype library:

https://github.com/jeapostrophe/exp/tree/master/foo

1) I use immutable hash tables to make object extension functional, and

2) Use static syntax bindings to give method names a first class
nature, rather than just using symbols. This allows independent
"traits" to use the same syntactic names but keeps them distinct, so
they can be renamed, etc.

If you want to see how to use syntax parameters to get 'self', my code
does that too.
