Here's a shorter version of bind than the one I mentioned from the book - it gets rid of the unnecessary loops.

if (!Function.prototype.bind) {
   Function.prototype.bind = function(o) {
   var self, bndargs;
   self = this;
   bndargs = Array.prototype.slice.call(arguments);
   bndargs.shift();
   return function() {
      var args = bndargs.concat(Array.prototype.slice.call(arguments));
      return self.apply(o, args);
      };
   };
};
