John, By convention, read . show is supposed to be id.
However, in real life, this is often not the case. It all depends on the implementor, and this is a convention that seems to be broken pretty frequently. Often there is a show instance with no read or vice versa, and sometimes even when there is both read and show they are not inverses. Thomas. main = show . read Am 7.
