I feel the same way about Clojure. For a LISP, where interactive development via the REPL is supposed to be one of the value-add of the language, it falls completely short in that aspect. They even have entire libraries and design patterns (Component, etc.) to work around the issue, but I find it ridiculous that your entire program structure is dictated by the fact that the REPL boot up time is too damn slow.
