Just a brainstorming
If the body does anything in new threads, e.g. in a pmap, then they won't be fast (or correct, if you reverse the defaults). I guess this a somewhat unrelated newbie question: aren't there often cases like this where one wants to temporarily rebind something, but across all children threads? Is there some straightforward way to do this that I've missed? -Lee -- Lee Spector, Professor of Computer Science School of Cognitive Science, Hampshire College 893 West Street, Amherst, MA 01002-3359 lspec...@hampshire.edu, http://hampshire.edu/lspector/ Phone: 413-559-5352, Fax: 413-559-5438 Check out Genetic Programming and Evolvable Machines: http://www.springer.com/10710 - http://gpemjournal.blogspot.com/ -- You received this message because you are subscribed to the Google Groups "Clojure" group.
