Not true. Compiling my-generator creates two classes, which at run
time are simply instantiated as needed. Here's an example:
(ns permgen.core
(:gen-class))
(defn -my-generator []
(let [x (atom 0)]
(fn [] (swap! x inc))))
(dotimes [_ 1000]
(-my-generator))
$ cake compile && ls classes/permgen/*
classes/permgen/core.class
classes/permgen/core__init.class
classes/permgen/core$loading__4410__auto__.class
classes/permgen/core$_my_generator.class
classes/permgen/core$_my_generator$fn__2474.class
