fix: class error when passing arguments

[gotneb]

Hi, Nguyen! 😊

Awesome project! I've been following your code while learning Rust, and it's been incredibly helpful. Thank you for sharing your work—it’s really helping me level up my skills.

I noticed an issue that occurs when arguments are passed to the init method in a class, and I’ve made a small fix to address it. Hope this helps!

class Player {
    // Construtor fails when arguments are passed
    init(name) {
        this.name = name;
    }

    run() {
        print("Player " + this.name + " is running...");
    }
}

//             <here>
var p = Player("Foo");
p.run();

Thanks again for the fantastic project!
