Using Point Free Style in Programming?

A point free style means programming where you don't have to name arguments or intermediate values. A, a p l family, haskall closure, an elixir, those all use it. It creates some really terse code that can be kind of obtuse hard to understand. So i want to ask you, are you using point free style anywhere in your code? Have you managed to eliminate an argument here or there that you didn't need to name? And then i'm also curious, because there's some really opaque code out there that's in point free style. I'm wondering what the worst you've seen is.
