or, the dreaded "no matching ctor found" exception.
Is there a way to write the function
(defn eval-at-one [f] (eval `(~f 1)))
such that it works when invoked like this:
(eval-at-one (fn [x] x))
;; --> 1
and like this
(eval-at-one (with-meta (fn [x] x) {}))
;; -> IllegalArgumentException No matching ctor found for class
clojure.lang.AFunction$1 clojure.lang.Reflector.invokeConstructor
(Reflector.java:163)
?
I thought that the object returned by with-meta might be hanging onto the
original, metadata-less object, which could then be retrieved and used
without difficulty, but this appears not to be the case.
