The letfn test is failing

[skydread1]

Problem

The mutual-recursion test fails in the namespace magic.test.letfn :

(clojure.core/= (letfn [(even2 [n] (neven? n)) (neven? [n] (if (zero? n) true (nodd? (dec n)))) (nodd? [n] (if (zero? n) false 

(neven? (dec n))))] [(even2 91) (even2 90)]) (magic.api/eval (quote (letfn [(even2 [n] (neven? n)) (neven? [n] (if (zero? n) true 

(nodd? (dec n)))) (nodd? [n] (if (zero? n) false (neven? (dec n))))] [(even2 91) (even2 90)]))))

  actual: System.NullReferenceException: Object reference not set to an instance of an object

 at <magic>magic_test_letfn$even2__0.invoke (:0)
    <magic>magic_test_letfn$<fn>__1.invoke (:0)

To reproduce :

nos cli-repl
user> (require 'magic.test.letfn)             
nil
user> (clojure.test/run-tests 'magic.test.letfn)
