A singleton method is associated with just one object. A singleton
method associated with a class object is a class method. Singleton
methods can also be associated with individual objects too.

   a = "fred"
   b = "barney"

   def b.succ
     "wilma"
   end

   a.succ  #=> free
   b.succ  #=> wilma
