Function application pipelines and function composition are closely related. Here's a "pipe" in Haskell: \x -> h $ g $ f x At a certain point you realise that in many cases seeing the `x` is not just useless but needless visual noise. The following is identical and more readable once you've internalised composition: h . g . f And this extends to a cute trick in which, if you need to explicitly provide that data to begin with, you can do this: h . g . f $ x I'm now working with Haskell having previously come from PHP and JS/TS. Composition is more readable, it's just harder to get started with because it's different to what you're used to. As for the "geek out" comment, of course, I enjoy programming for the intellectual sake of it. I'm not product-driven. Don't make the mistake of thinking everyone's the same as you, nor that of thinking there aren't benefits to being so intellectually-motivated. I don't know if it's intentional but your comment comes across as rather self-righteous.
