Subject: Overloading math operations


Hija,

been makin a little "Vector" class by extending Array.
Now I wanna add Vector support to the native numeric
data types in ruby. Means: Not only Vector+Numeric
but also Numeric+Vector should call my + function.

But I have a syntax prolem.. :-(

Example (not working!):

class Fixnum
  alias old+ + # here i have the syntax problem
  def +(other)
    if (other.class<=Vector)
      other+self
    else
      self.old+(other)
    end
  end
end

Someone please help poor ruby nooby! :-)))

Regards, 0ffh
