better error messages for bad defrecord calls

Question

defrecord could tell you if, e.g., you didn't specify an interface before leaping into method bodies.

(defrecord TestRecord [afield bfield cfield] (printc [_] (println cfield))) ClassCastException clojure.lang.PersistentList cannot be cast to clojure.lang.Symbol clojure.core/ns-resolve (core.clj:4238)

stu said: This could be fixed with an assert-valid-defrecord call in core_deftype, similar to assert-valid-fdecl in core.clj. Such a function would also be a place to hang other defrecord error messages.
