You raise a really good point here. One can force sharing, as I understand it, by using a let clause: n = let xs = f 20 in length (xs ++ xs) If I understand correctly, this should cause xs to be first evaluated, and then cached until the full length is computed, which in this case is obviously undesirable behavior.
