As configured in my dotfiles.

start new:

tmux

start new with session name:


	(defn create-function-call [param expr]
	"Create an sexp for calling expr with a first argument provided by a promise.
	If expr is a list (already in form suitable for a function call), insert the first argument at second position,

	println -> (fn [param] (println param))

	(* 2) -> (fn [param] (* param 2))
