Paredit might seem weird at first, but it really makes writing lisp a
much more comfortable experience. This is especially useful in
combination with the sexp movement functions (C-M-f
forward, C-M-b
back, C-M-u
up, C-M-d
down)

Prettier function names in clojure – Thanks to Paul Hobbs for the
idea to extend this feature beyond simply the fn
function.
