Shamit Kumar Tomar Nice and small code. Like it.

Peter Isn't printf an invocation of Java? It doesn't look "clojury" to me. Java has proprietary formatting mechanism, but it also includes the printf method for its concise syntax.

Rayne printf uses Java's format under the hood. So what? "Where Java isn't broke, Clojure doesn't fix it." is a huge Clojure philosophy. This is perfectly 'Clojury'.

Rayne Except for putting the closing parens on a separate line. That's just stupid.
