For those who want to play with this without keeping two versions of
their source code files, I have added a new macro lazy-and-standard-
branch to clojure.contrib.macros. Here is an example of how to use it:
(lazy-and-standard-branch
(defn value-seq [f seed]
(lazy-seq
(let [[value next] (f seed)]
(cons value (value-seq f next)))))
(defn value-seq [f seed]
(let [[value next] (f seed)]
(lazy-cons value (value-seq f next))))
)
Konrad.
