I just read several tutorials on iteratee, i find that iteratee is similar to python's generator, both allow streamlined data processing. For example, i can implement enumFile and printChunks in python like this:

    EOF = None

    def enum_file(bufsize, filename):

        with open(filename) as input:

            while True:

                data = input.read(bufsize)

                if not data:

                    break

                yield data

        yield EOF

    def print_chunks(print_empty, generator):

        for chunk in generator:

            if chunk==EOF:

                print 'EOF'

                return

            if len(chunk)==0 and not print_empty:

                continue

            print chunk

    print_chunks(True, enum_file(2, "data"))

But i find iteratee far more complicated than python's generator, is that because iteratee can do something python's generator can't, or i simply need to be more familar with functional programming style.
