> 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.
Would it work to wrap the whole thing (including any `finally`s) in a
handler that discards surviving `ExitSuccess`es by default, with a flag to
disable the default wrapping?
