 No, when you write

   case a
   when b
   end

  ruby call b.===(a)

 This mean that in this case it call Module#===

 Kernel is a module which is included in Object (see p. 356)

  "Object mixes in the Kernel module, making the built-in kernel functions
  globally accessible. Although the instance methods of Object are defined
  by the Kernel module, we have chosen to document them here for clarity."
