Too bad, if that's really the final word. It's so very useful to get the locals at the point of (unanticipated) error, and this is information that is already "known" to the system... and we just want it not to throw it away. > The lesson for clojure developers being, strive for reproducibility!

My domain (mostly research in evolutionary computation) is indeed inherently "going to produce hard-to-reproduce circumstances." And, as it happens, logging that is sufficiently "aggressive and detailed logging" to capture the things I'll want to see after a crash would produce astronomically (impractically) large log files. It'd be so much nicer just to see the values of the locals at the time of the crash, which are already there in memory if we could only grab them in time. -Lee -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
