Hi Jan, I'm not familiar with Weld, but based on the error message shown the cause might be the recent changes in making sequences fully lazy.
Which version of clojure.contrib are you using? If it works for Mark, you might want to make sure that you're running the same version of Clojure and clojure-contrib as he does. Also, try to do troubleshooting from the command line REPL and not through SLIME to isolate the side effects your SLIME/clojure-swank configuration might cause.
