// Make me compile! Scroll down for hints :)

fn main() {

// This main function is calling a function that it expects to exist, but the
// function doesn't exist. It expects this function to have the name `call_me`.
// It expects this function to not take any arguments and not return a value.
// Sounds a lot like `main`, doesn't it?
