(defun clojure-reset-namespace ()
  "Reloads the current Clojure namespace by first removing it and
then re-evaluating the slime buffer. Use this to remove old
symbol definitions and reset the namespace to contain only what
is defined in your current Emacs buffer."
  (interactive)
  (save-buffer)
  (slime-interactive-eval (concat "(remove-ns '" (slime-current-package) ")"))
  (slime-compile-and-load-file))

(defun clojure-switch-repl-to-current-namespace ()
  "Switch the REPL to the current clojure files namespace"
  (interactive)
  (slime-repl-send-string (concat "(ns " (slime-current-package) ")")))

This clojure-reset-namespace version shows compiler errors better.
