I'm glad I'm not the only one who thought this. When I first learned about function composition, a supposedly groundbreaking feature of functional programming, Unix pipes were the first thing that popped into my head, but making that comparison out loud was only met with facepalms and accusations of trolling. But it's literally 'take this input and apply these functions to it, in this order'.
