Also, my version of the "split but don't drop the delimiter" is
breakAll, since it's like a recursive break.
words/unwords and lines/unlines have one argument, so a 2 argument
fielts/unfields would break that "convention". Maybe:
fields = csv `separateWith` ","
csv = fields `joinWith` "," -- equivalent to concatIntersperse
