For anyone who is interested, here's the definition (and some side
notes about how it evolved).

  def mash(&yld)
    if yld
      inject({}) do |h, *kv| # Used to be inject({}) do |h,kv|
        r = *yld[*kv]        # The *-op works different from to_a on
single element hash!!!
        nk, nv = *r          # Used to be nk, nv =
*yld[*kv].to_a.flatten
        h[nk] = nv
        h
      end
    else
      Enumerator.new(self,:mash)  # Used to be Hash[*self.to_a]
    end
  end
