I think it's very likely there's a simpler way to do this with
Data.Serial as written, I am just a little backwards with state
monads and that kind of thing.
OK, another look at it reveals that "mplus" can be used for this
application, so much more simply,

    import Control.Monad (mplus)

    getx = do
	a <- get
	x <- getn `mplus` return []
	return (a:x)
