If you read the most introductory guide of Haskell, or ask your LLM to explain, you'll find there's nothing mystifying about the syntax you quoted. You're just unfamiliar with it because you didn't do the bare minimum effort.

If I ask my grandma what she thinks of the supposedly easy Python syntax, or C-style curly braces, her brain would similarly crash. Unless she read an intro to Python or C first.

In other words, do not confuse "I'm unfamiliar with this because it doesn't resemble what I know" with "hard to understand".
