			function myNew(constructor) {
				var obj = {
						__proto__: constructor.prototype
					};
				constructor.apply(obj, Array.prototype.slice.call(arguments, 1));
				return obj;
			}

			function MyTest(i) {
				this.count = i;
			}

			var obj1 = myNew(MyTest, 0);
			console.log(obj1.count);
			console.log(obj1 instanceof MyTest);
			console.log(obj1 instanceof Object);

			function OtherTest(i, name, value) {
				this.count = i;
				this.name = name;
				this.value = value;
			}

			var obj2 = myNew(OtherTest, 0, 'myName', 'myValue');
			console.log(obj2);
			console.log(obj2 instanceof MyTest);
			console.log(obj2 instanceof OtherTest);
