Re: Request for improved error reporting

I have no experience with gradual typing, but I'd love to try it. It seems there are many situations where dynamic typing just makes things easier than in a language like Haskell, however I long for their ability to verify correctness at compile time. Vince On Mar 29, 10:49 am, André Thieme wr

Re: java faster than clojure?(probably not)

ng" my reader functions to fns (see compile-field and compile- record in unpack.clj) I hope some of these help. I realize that not all are directly applicable to your case, but I figure other people may find them useful. Cheers, Vincent. On May 9, 6:53 pm, Julien wrote: > I'm in
