[Newbie warning on] Here's a few random obeservations from my playing with Haskell: You've got into Haskell with unusual rapidity. Most of your observations are fairly aimed.
Recently found a memoization modulue in Hugs, but no docs. There's a reference to the Haskell '97 Report, but I didn't find it online. http://www.cse.ogi.edu/~jl/ACM/Haskell.html http://www.cse.ogi.edu/~byron/memo/dispose.ps
7. There's a lot of discussion w.r.t state, at least on this list. Is threading state through many functions respectivley polluting many functions with monads the solution? If a function is pure, there's never any need to involve it with a monad. Monads don't cause "pollution". They serve to indicate what functions have side effects, while the choice of monad tells what kinds of side effects may occur.
Haskell people enjoy pure functions, but are not shy of side effects, which are recognized as an essential feature of every program. Functions that return monadic values provide an excellent way to organize side effects.
