Average Rust code:

macro_rules! sum {
    ( $initial:expr $(, $expr:expr )* $(,)? ) => {
        $initial $(+ $expr)*
    }
}

fn remove_prefix<'a>(mut original: &'a str, prefix: &str) -> &'a str

let mut up = 1;
    'outer: loop {

This is on the level of the esolang I made at 8 y/o, with random characters denoting random actions everywhere, at random positions.
