i just happened to be working on this today

   jib:~/eg/ruby/alib/alib-0.3.1 > cat a.rb
   require "alib"

   oh = ALib::OrderedHash::new

   ("a".."z").to_a.reverse.each{|x| oh[x] = x}

   oh.yaml_inline!

   y oh


   jib:~/eg/ruby/alib/alib-0.3.1 > RUBYLIB=./lib ruby a.rb
   --- { z: z, y: y, x: x, w: w, v: v, u: u, t: t, s: s, r: r, q: q, p: p, o: o, n: n, m: m, l: l, k: k, j: j, i: i, h: h, g: g, f: f, e: e, d: d, c: c, b: b, a: a }


the class is in alib now, but the yaml_inline will break on 1.8.4.  releasing soon.

cheers.
