Subject: chaining methods

Hi,

I'm looking for a nice way to chain methods in an API I'm writing.

I'd like to be able to write
   r.width=5.height=6
, but then the receiver of height= is 5.

So I have to write
   (r.width=5).height=6
; the first expression returns a Rect.

   def height= value
     add_attributes('height'=>value.to_s)
     self
   end

What would be a simple way to make it possible to chain the above methods?

Tobi
