From TFA, on combinators vs. loops:

    items.iter().enumerate().filter(|(_, i)| cond(i)).map(|(idx, i)| Pointer::idx(i, path, idx)).collect()

    while (i < cursors.len) {
        if (actual_index < arr.items.len) { cursors[i] = .{...}; i += 1; }
        else iteration.remove(i);
    }

I’ve been slowly learning Rust, and this style is my main gripe against it, because I feel like I’m being gaslit. Its proponents praise its readability and ease of use, and just… no. It looks deranged. A simple loop is immediately obvious to anyone who’s programmed in any language. Even Python’s list comprehensions are loop-ish.
