I propose the addition of the following two functions to module Debug.Trace:
> traceM :: Monad m => String -> m ()
> traceM msg = trace msg (return ())
> traceShowM :: (Show a, Monad m) => a -> m ()
> traceShowM = traceM . show
These functions allow tracing in any do-block. I often define them
myself; I think they are useful in general.
Deadline: 23 October 2009.
