But the longer answer would be, it depends! Right? The `do' notation
is clear and easy to follow; it's low maintenance - even if you have
nothing to bind right now, if that comes up in the future, it will
drop right into that `do' block; it's classic Haskell that doesn't
need any explaining to (hardly) anyone. Maybe it's your last choice,
maybe it's my first.
