defprotocol: emit less opaque validation errors

Question

Hi,

I'm getting one of these https://github.com/clojure/clojurescript/blob/23ab9a095599446e3c2aa5013d2b8edf2bbe467f/src/main/clojure/cljs/core.cljc#L2043 , out of a defprotocol-emitting macro which works perfectly in JVM Clojure.

It would be useful if the error included the value at fault, rather than just saying "received unexpected argument".

Thanks - V
