After writing the previous post, it struck me that memoization could be done at the function level. If each function had an associated Map <Arguments> <Result>, lookup would be much simpler and more localized. One could then decide on a function-by-function basis which maps to expand. * -- Russ *
There are packages on hackage to memoise functions, e.g. http://hackage.haskell.org/package/data-memocombinators You have to decide yourself which functions to memoise, there are no good heuristics for the compiler to decide, as far as I know.
