Subject: [ruby-talk:9584] 3 + 2.im works!  why?

Hi,

As you probably all know.  This works:

	irb> require 'complex'
	true
	irb> 3 + 2.im
	Complex(3, 2)

But my question is: why does this work?  What is going in ruby's head?
As I understood from `Programming Ruby' 3 + 2.im is equivalent to
3.+(2.im).  I don't see fixnums having a method that adds complex
numbers, so is 3 converted to a complex.  No, ruby would not know how
to do that, would it?  So, maybe ruby changes this to (2.im).+3?

I don't know, you tell me.

regards,
Richard
