As far as I've understood it, in Ruby it's not about what the type is 
but what the type can do. i.e. does it respond to a specific method. So 
maybe generics in Ruby would make sense if you could restrict objects 
based on what they can do. For example an array which can only hold 
obejct that respond to the to_str method.
