[Haskell-cafe] Is this haskelly enough? -- errm but every answer is wrong(?)

(Or at least the problem is under-specified.) 1. There may be several sub-sequences having the maximum sum. So the type for the solution should be :: Num a => [a] -> [[a]] (Note that the problem didn't ask for the maximum itself.) 2. The inits . tails approach adds a fault: It introduces a sprinkling of empty sub-sequences. These have sum zero. So in case the input list is all negative numbers ... Being a software tester for my day job, I looked first not for an elegant and/or efficient solution; but for where to stretch the boundaries of the problem.

However, the key point is that this is a TRICK QUESTION.
