Small arrows tutorial (sorta, I'm learning myself and trying to doc as I go): http://www.thenewsh.com/~newsham/x/arrow.txt comments welcome. I ran into a type issue I couldnt resolve. I'd love any comments on that (documented near the bottom, liftA2'). Also, I'd like to put some info about ghci -farrows syntax when I figure that stuff out. If anyone feels like translating some examples into do-notation or coming up with new examples that showcase do-notation, please post em or send them to me.
