Plus, powerful abstractions that make the code look simple and elegant _always_ come at a price. An Arrow-based stream processor that performs the same task as my monadic BlockIO library does, for instance, results in a module that has half the size the StateT version does. Which is cool. But it is, as of now, also 10 times slower than the monadic version is. Which is not cool at all.
That's indeed a rather high cost. Although I suspect that a lot more effort has gone into optimizing Monads than into optimizing Arrows... Cheers, Remi -- Nobody can be exactly like me. Even I have trouble doing it.
