Re: [Haskell-cafe] Question about the Monad instance for Iteratee (from the enumerator package)

John Lato's "iteratee" package is based on IterateeMCPS.hs[1]. I used IterateeM.hs for "enumerator", because when I benchmarked them the non-CPS version was something like 10% faster on most operations. The new IterateeM.hs solves some problems with the old encoding, but I haven't switched "enumerator" to it yet because it would break backwards compatibility.
