Rust: A Critical Retrospective

Is the syntax really that much of a burden? I don't have a perfect grasp of the syntax and would have trouble if I was having to write rust code with zero reference, but as long as I have other rust code open it is pretty easy to remember what each part does.

It's just hard to parse

    fn apply<A, B, C, G>(mut f: impl FnMut(B) -> G, a: A) -> impl FnMut(&B) -> C
    // must still be `for<'r> impl FnMut(&'r B) -> C`, because that’s what filter requires
    where
        G: FnMut(A) -> C,
        B: Copy, // for dereferencing
        A: Clone,
    {
        move |b| f(*b)(a.clone()) // this must do any bridging necessary to satisfy the requirements
    }

I wrote this code myself, and it's SLOW for me to read. Each part isn't hard, it's just too much crap
