Ruby overload + operator

What is the right way to overload operators in ruby? What do I need to do to redefine how + works? This function isn't being called when the + operator is used.

def +(a,b)
 return a * b
end

p 2 + 2

Overloaded operator is resolved based on the class of the first operand, so if you wanted to overload the addition of simple integers, something like that should work:

class Fixnum
  def +(other)
    return self * other
  end
end

I do not recommend you to actually do this, btw.
