Notice it says "can't recur from within a catch". So throw the try/catch into it's own function and return nil if the try fails. Then throw a if statement to continue the loop only if the function return nil. Timothy On Thu, Mar 17, 2011 at 8:49 PM, Fiel Cabral wrote: > Hello Clojure users, > T

That explaination makes sense. Still, it goes against my mental model to think of each thread as a member of only one namespace at a time--I guess in my mind it seems like a lexical, rather than dynamic property. But again, I suppose that might be a sign that operating on *ns* directly is not the b
