With do notation, I can write something like this:

do foo <- callFoo x bar <- callBar x return (baz)

... The short answer is to write a "one liner" using (>>=) and (>>), unless you need to bind more than one value to a variable. In that case, you should use an applicative interface, if available and otherwise possible, and finally do-notation.

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. Donn
