The ` for ' trick definitely worked. Unfortunately that solves my

This sets the namespace for your new thread before it evals. You also
might want to take a look at clojure.lang.Repl for an example of how
to create a REPL, also repl

The eval executes the code in the clojure namespace. You have to fully
qualify your tst function. The easiest way to do this to use ` instead
of '. So using `
I've hit another mystery (to me), that I hope someone can explain.
Why doesn't the following work?
(defn tst[] (pr 4))
(defn trd[]
(let [f #(eval '(tst))]

It seems that a separate thread can not EVAL any defined functions. If
I change the above to remove the thr
