I'd prefer something implemented in terms of sprintf.

Feature #8573: Add String#format method(not an alias of String#%)

I think it'd be great if String included a method similar to `%` that accepts variable number of arguments (like `sprintf`). This is trivial to implement as you're certainly aware.

Here's one implementation suggestion:

  class String
    def format(*args)
      super(self, *(args.flatten))
    end
  end
 
This would make the new method behave both like `sprintf/format` and `String#%`. I think this minor improvement would definitely be in the spirit of making more programmers happy :-)
