I the new version which I think is cool:

------------------------------------------------------------- Range#step
      rng.step(n=1) {| obj | block }    => rng
------------------------------------------------------------------------
      Iterates over rng, passing each nth element to the block. If the
      range contains numbers or strings, natural ordering is used.
      Otherwise step invokes succ to iterate through range elements. The
      following code uses class Xs, which is defined in the class-level
      documentation.

         range = Xs.new(1)..Xs.new(10)
         range.step(2) {|x| puts x}
         range.step(3) {|x| puts x}

      produces:

          1 x
          3 xxx
          5 xxxxx
          7 xxxxxxx
          9 xxxxxxxxx
          1 x
          4 xxxx
          7 xxxxxxx

Hope that helps.
