Yes, I think it is a nice feature. But why do you use the word "renaming"?
`exact-pi' in the above example is not only a new symbol, it is also bound
to a _copy_ of pi's value.


       (set-current-module (A))
       (set! pi 100)
       (set-current-module (C))
       exact-pi -> 3.1415
       pi -> 100
