Also, any trailing non-numeric characters (as in --resume 9r) will be ignored, as this code just blindly calls fst if reads returns anything but an empty list (don't know if this is stupid or not).
What's the motivation for this? The core outside of StackSet.hs isn't h98 -- and won't be. I can understand removing them from StackSet.hs, to allow Catch/YHC to work on that module (though they're also adding pattern guards to nhc/yhc iirc), but given the non-StackSet.hs modules aren't H98 anyway, I don't see what benefit we get from this. Pattern guards are useful, concise, have been around since 1997, and feel free to use them. -- Don
