Javascript function binding crap

FunctionBinding.js

// Define a class with a method
function MyClass(value) {
    this.value = value;
    this.function = function() {
        return this.value;
    };
}

// Instanciate the class
my_class = new MyClass("my value");

// Pass the method as a callback to the timer
window.setInterval(my_class.function, 1000);

// Sadly, we get an error 'cause window.value is undefined.
