My students who did Haskell last year all passed with flying colors. I think the examples above are plenty clear, and the students also found them clear after I explained them, and with enough practice it wasn’t an in issue. I read the literature, practice it, and then use my teaching skills to teach it. It’s my job, and I take pride in what I do.

I’d say maybe the hypothetical you just needs a good teacher to show how it’s done, or the hypothetical student needs to read it enough till you understand it. In math we also have symbols, in math we also use shorthands. Why not in compsci?

Bar that, Haskell is just not a language that’s suited as a first language. The literature expects from you to be able to understand technical manuals. You don’t go teaching Rust to 8th graders, you don’t go learning Haskell without knowing at least what currying means.

As for brackets, you’re free to put them wherever you want; the professional are also free to do what they want, and it’s usually a good idea to adhere to a standard.
