By the way, related to one space indent, is any other editor but Emacs (clojure-mode) using it?
I've been trying to configure Fireplace use it but while it's possible, it requires listing all "special cases" which are indented with 2 spaces so I'm not sure if it's worth effort
@juhoteperi: Cursive has a mode to enable it for people who need their indentation to match Emacs, but IMO it should not be the default in Clojure (which almost never uses lists for data, but always uses them for code).
