Setup

var emulatebind = function (f, context) {
      var curriedArgs = Array.prototype.slice.call(arguments, 2);
      if (curriedArgs.length) {
        return function () {
          var allArgs = curriedArgs.slice(0);
          for (var i = 0, n = arguments.length; i < n; ++i) {
            allArgs.push(arguments[i]);
          }
          f.apply(context, allArgs);
        };
      } else {
        return createProxy(f, context);
      }
    };
    
    function createProxy(f, context) {
      return function () {
        f.apply(context, arguments);
      }
    }
    
    var i = { i: 0 };
    
    var f = function () {
      this.i++;
    };
    
    var binded = f.bind(i);
    var emulated = emulatebind(f, i);
