Note that I tried to add this to your test :

  t.report("=") do
    10000.times do
      a = Array.new(100)
      100.times do |x|
        a[x] = x
      end
    end
  end

And...

Rehearsal --------------------------------------

[]   0.031250   0.000000   0.031250 (  0.027802)

         user     system      total        real
<<   0.304688   0.000000   0.304688 (  0.309506)

Surprising !
