Hi everyone, This is not an attempt to start a flame war. I'm just trying to get a good feel for the advantages and disadvantages of the newer safe lazy io lib available on Hackage vs using Iteratee. It does appear to me that using something like Itereatee gives a bit of room to really tweak the low level enumerator/iteratee relationship, and, if you asked my old boss, I'm just a big fan of folds too, I use them a lot in my Erlang :-), so Iteratee really does appeal to me on many levels. Yet at the same time, I'm quite enamored with the beauty of "interact" and functions of that sort. I realize mixing the effects of the lazy IO and pure code may not be the clearest way to write code for everyone, but there is something about being able to get linewise data as interact (unlines . fmap someLineWiseFunction . lines) that is just kind of cool.
