Hi all,

I'm playing around a bit with arrows (more specifically, something like a CPS style streamprocessor as described in "Generalising Monads to Arrows" by John Hughes).

I had struggled with the same problem a year ago, and I concluded it was hopeless. See http://www.haskell.org/pipermail/haskell-cafe/2010-January/072193.html The only stream processors that conform to the Arrow interface seem to be the FRP-like ones, where each stream item comes with a time stamp. I'm not entirely convinced that Arrow is the best abstraction even in that case.
