And in the event that you some arguments to B that
A does not know how to handle, use the second form:

 class A
   def initialize(foo)
     puts "initializing instance of A with #{foo}"
   end
 end

   def initialize(foo, bar)
     super(foo)
     puts "initializing instance of B with #{foo} and #{bar}"
   end
