Why build up a separate hash structure?

def Enumerable.max_by
  ps = nil
  inject do |pmax, a|
    s = yield a
    if (ps == nil or s > ps) then
      ps = s
      a
    else
      pmax
    end
  end
end



-- 
s=%q(  Daniel Martin -- martin@snowplow.org
       puts "s=%q(#{s})",s.map{|i|i}[1]       )
       puts "s=%q(#{s})",s.map{|i|i}[1]
