ClojureScript commit 0df1bc4d7bdf4d411e72d443b5a23d146d5e64b8 on JDK 1.6 on Mac OS X (Lion)


When reifying a protocol, the created object cannot be annotated with metadata.

(defprotocol IFoo (foo [this]))

(with-meta (reify IFoo (foo [this] :foo)) {:foo :bar})
"Error evaluating:" (with-meta (reify IFoo (foo [this] :foo)) {:foo :bar}) :as "cljs.core.with_meta.call(null,(function (){if(cljs.core.truth_(cljs.core.undefined_QMARK_.call(null,cljs.user.t4972)))\n{\n/*\n @constructor\n*/\ncljs.user.t4972 = (function (){\n})\ncljs.user.t4972.prototype.cljs$user$IFoo$ = true;\ncljs.user.t4972.prototype.cljs$user$IFoo$foo = (function (this$){\nvar this__4973 = this;\nreturn \"?'foo\";\n});\n} else\n{}\nreturn (new cljs.user.t4972());\n})(),cljs.core.ObjMap.fromObject([\"?'foo\"],{\"?'foo\":\"?'bar\"}));\n"
