So the current idea is:
withTrace :: Show a => a -> a withTrace x = trace (show x) x
Does anyone have anything else to add?
I would expect
withTrace :: Show a => String -> a -> a withTrace str x = trace (str ++ show x) x
to be more useful.
I agree. It's easy enough to do withTrace "" if you don't want a message. Sean
