Ruby-like string interpolation in Clojure
View ruby-fmt.clj
; Ruby has an awesome feature -- string interpolation. Read about it on the internet.
; On the other hand, Clojure only has cumbersome Java string formatting, which can not be
; used without pain after you've tried Ruby.
; So here's this simple macro that basically allows you to do most things you could do
; with Ruby string interpolation in Clojure.
