When I look at this, it confuses me.  First of all, why does r.width=5
return a Rect?  I think it should return 5, otherwise I cannot do:

   r.width = r.height = 42

As a solution, just use two separate statements.  It will be easier to
read and less of a headache later on when you are trying to figure out
what this does.
