[racket] CLOS-like multiple dispatch over types

Hi Roman,

Regarding the package site... I can't find a log entry for your
account creation attempt. Is it possible you can send me the output of
the Javascript console? Maybe you didn't type in the same password
twice or something and the request never left your browser?
