Code review comment for lp://staging/~leonardr/lazr.restfulclient/server-takes-precedence

I have reservations about letting objects change type, but leonardr has convinced me that this is not a practical problem. The discrepancy would be hard to provoke, because accessing members will cause the object to be loaded.

I would like to see mention in the documentation that WADL doesn't allow inheritance relationships to be explored. Otherwise, this is fine.
