Ruby does not allow writing of another method with the same name. So, overloading is not possible in Ruby. However, you can be crafty in a way of overloading a method by utilizing and extending with new logic within an existing method.

For instance, you want to change how one class handles parameter.

Class MyClass
 def initialize(*args)
 case
  when 2
   @var1, @val2 = *args
  when 3
    @var1, @var2, @var3 = *args
  else
    raise ArgumentError, “This is an error to have more than three and less than two arguments”
 end
end

Create an instances with this class can be done in the following manger without too much troubles

MyClass.new(1,2) //OK
MyClass.new(1,2,3) //OK
MyClass.new //produces an error message

We could have added Duck Type checking to this class above for more elegant code as well.
