Lazy Non Cashing or Lazy Cashing?

Lazy cashing is conceptually a simpler programmatic model than lazy non cashing. Lazy non cashing gives you more options but can be a lot more confusing. In closer, if i'm doing a map followed by a filter, we're not going to cash the intermediate result. That's the way closer corp is designed. But in haskell, there is a way that you could write a closur corps style map and filter pathway that is lazynon cashing. And thus can combine the map function and the filter functions together in a dense piece of code.
