I'm confused about the last paragraph. I agree that it is surprising that you can eliminate tuples entirely once you go to N-ary functions and constructors, but it seems that to avoid blow up (in the sense of unbounded extra allocation) you need to know that dynamically you don't use it in such things. Not statically. Also, you inc the count on selects? This would seem to break fun z = let val x = #1 z # first use of z val y = #2 z # z is now MANY ... Have I missed something? |
