I'm thinking about implementing a backtracking mechanism that throws errors as a way to escape out of the current computation and try another possibility. I'd want to create a specific error to escape, and the backtracking mechanism should only catch this very specific error.
Now, I vaguely recall some thread on here a while ago about how this is very hard to do in Clojure, because Clojure wraps the errors inside of other errors as they work their way outwards, so you can't just catch a very specific error. I think there was some sort of workaround involving catching every error, and looking deep inside the stack of errors to find the specific error, and if not found, pass it on up the chain. Am I remembering this "gotcha" correctly? If so, can someone please spell out the workaround for me again? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
