Let's look at this example:
(defmacro defgreeter [greeter-name]
(let [greeter (java.util.Random.)]
`(defn ~greeter-name [user-name#]
(.nextInt ~greeter))))
It fails with
Can't embed object in code, maybe print-dup not defined:
java.util.Random@1572aa51
How does this error relate to OP's? Since here printing does seem to be
involved.
