I present to you quality variable names. (and a Mount Rustmore)

(Reconfigure(f), 'c') => {
    let mut p: Vec<&str> = vec![];
    loop {
        match args.next() {
            Some(k) => {
                if k == "=" {
                    match args.next() {
                        None => q("need value for Rc"),
                        Some(v) => u(
                            f,
                            |f| Box::new(
                                |c| {
                                    f(c);
                                    c.set(p.iter().copied(), v);
                                    for e in p {
                                        unsafe {
                                            Box::<str>::from_raw(
                                                std::mem::transmute(e)
                                            );
                                        }
                                    }
                                }
                            )
                        )
                    };
                    break
                } else {
                    p.push(Box::leak(k.into()));
                }
            }
            None => error("need path element or = for Rc"),
        }
    }
},

Ok, but what variable is 🐈?

It took me too long to figure out the I in an if statement was just integer

Am I being gaslit?
