How about this?

==========================================
class Cla
        def initialize(hash)
                hash.each do |key,value|
                        type.send(:attr_accessor, key)
                        send(key+'=', value)
                end
        end

end

hash = { "uno" => "one", "dos" => "two"}

c = Cla.new(hash)
