I don't deny that there are many people like you in the programming world who struggle to understand things that many others have no trouble at all grokking. But my observation is that there are far more people like me, who don't struggle with understanding OO code. For decades, OO has been the dominant programming paradigm. And for decades, functional programming has been, as declared by many, on the cusp of taking over the world. And yet it never seems to happen.
