We are aware that this is a breaking change. :-) In addition to talking on IRC and the mailing list, we checked dozens of Clojure libraries (code review and test suite) and found *minimal* breakage. If anyone has different empirical evidence to offer, please do so. Stu -- You received this message because you are subscribed to the Google Groups "Clojure" group.
