Hi Crutcher, I have some enumerator debug code here: https://github.com/snapframework/snap-core/blob/8c9b7098751784b9d88dff68524ed2558c03c3d8/src/Snap/Internal/Iteratee/Debug.hs It's a little bit snap-specific (uses our debug machinery) but helps me a lot when debugging iteratee stuff. Shouldn't be hard to port. It contains a debug iteratee (which just prints its input to stdout) and an iteratee wrapper which logs its input using the Snap debug mechanism before passing it on to the wrapped iteratee.
