class A

  def initialize(arg1, arg2, hash)
    hash.each do |key, val|
      A.send(:attr_accessor, key)
      send("#{key}=", val)
    end
  end

end


a = A.new("hello", "world", :x => 10, :y => 20, :z => "red")
puts a.x
puts a.y
puts a.z

--output:--
10
20
red

a.x = "hello"
a.y = "goodbye"
a.z = "the end"

puts a.x
puts a.y
puts a.z

--output:--
hello
goodbye
the end
