Arrows in Haskell are actually pretty good at building functional left to right data processing pipelines.

Yeah for sure! The tricky, prickly part of talking about FP is that we get into semantics a lot (eg. I'm sure there's Haskell experts who wouldn't consider JavaScript's `Array.prototype` functions to count as FP). Generally I'm thinking about `foo.map` vs. `for n in foo...`. Maybe "imperative" is a bit of a loaded term for this point.

Arrows [1] are great, not sure why you were getting downvoted on that.
