In Clojure, a map entry created within a macro is preserved...

(class (eval `(new clojure.lang.MapEntry :a 7)))
;=> clojure.lang.MapEntry

...but when piped thru from the outside context collapses to a vector...

(class (eval `~(new clojure.lang.MapEntry :a 7)))
;=> clojure.lang.PersistentVector

This behavior is defined inside LispReader.syntaxQuote(Object form) condition if(form instanceof IPersistentCollection).

Does anyone know if this is intended behavior or something that will be fixed?

I'm attempting to use deftype (from the bleeding-edge clojure 1.2 branch) to create a java class that implements the java Servlet interface. I would expect the code below to compile (even though it's not very useful). (ns foo [:import [javax.servlet Servlet ServletRequest ServletResponse]]) (deftype… >>> More
