I agree with you, John.  Personally, I find the CPS version easier to
use, that's why I asked.  But since people have different styles, I
guess it's not a bad thing that the two packages use a different

When I was reimplementing Iteratees I also didn't find any noticeable
slowdown with CPS, but my benchmarks were very simple -- unlike yours.
 You are comparing the darcs branch to the version on Hackage, right?
