Beautiful, specification orientated, composed of abstract components.
My thoughts too when reading the initial post was that it was all very low level imperative programming. Not of the Haskell flavour.
I remember there was a discussion about how to implement full 'wc' in an elegant but maximally lazy form, that is counting bytes, words and lines in one go. Did someone have a nice idea of how to compose the three counters from implementations of each counter? I'm afraid one cannot simply use the "split and count fragments" trick then.
