It's really cool !!!!

Just an issue: the above code don't allow multiple attributes definition:

  attr_accessor :atr, atr2

=> `attr_accessor': wrong number of arguments (2 for 1) (ArgumentError)


I don't remember now what must I do to take all the possible arguments
as an array, could you point it to me please?

thanks a lot.
