Title: //(x::Rational, y::Rational)

As was brought up in the list, I suppose I have added the operator // to work with rationals. I mean, I only added one line to the /base/rational.jl. I am not sure if I needed to change anything else.

Sorry to bother if this is wrong. I tested only by loading the function in a section.
