daily dose of js wat

lol.js

function C(a){
    this.a = a
    this.f = function(){ print(this.a); };
}

o = new C('racecar');
o.f() // prints 'racecar'

a = o.f
a() /* prints:
    *   function () {
    *       print(this.a);
    *   }
    */

/* Yes, a() prints itself, because `this` in a's function body 
 * references global. global.a is the function a, and not 'racecar'.
 * o.f isn't bound to its receiver (o) when it's assigned to a.
 * Because, JS.
