Hi, I want to order a hash using itds keys:

  irb> a = { 2=>"2", 3=>"3", 1=>"1" }
  irb> a.sort
  [[1, "1"], [2, "2"], [3, "3"]]

But I want a resulting hash with keys ordered:

  { 1=>"1", 2=>"2", 3=>"3"}

Is there any efficiente way? (I don't want the hast to be converted to
an array and the to a hash again).

Thanks.
