By watching (println) the experiment we influence the outcome. Is the Schrodinger's cat present in Clojure?
This example program that shows how printing a value can change the value under specific circumstances. It seems the case that it has to do with the lazy evaluation that happen in Clojure. Basically I map a pr-str over a list. When I print the list before realization it seems that println is modifies the value. Doing a doall or turning the lazy-list into a vector makes the circumvents the issue. The code showing this behavior is is attached. Loading the file will show the issue. I've tested it in Clojure 1.5.1, Clojure 1.6.0. I also tested it in Clojure-clr 1.5.0, and observed the same issue. Please let me know whether this is expected behavior, a known issue, or a new one.
