I've been writing Clojure lately but I'm a greybeard (literally) Vi/Vim user. vim-fireplace is nice but I can't help wonder if I'm losing something by not using Emacs. At the same time, Clojure is so wonderfully different from the other languages I know that I don't feel like I have the cycles to learn a new editor at the same time I'm learning a new language. Then again, maybe that's the best time to learn Emacs?
