Comment (by simonmar):

 Replying to [comment:2 NeilMitchell]:
 > I'd suggest that no output is appropriate. The fact that exit success is
 implemented as an exception is an internal detail, as exceptions are
 typically for exceptional conditions. It also mirrors the standalone
 behaviour, which is a good thing.

 It's not just an implementation detail - the fact that `ExitSuccess` is an
 exception means that you can use things like `Control.Exception.finally`
 to run code on program exit, regardless of whether the program exits
 successfully or not.
