Using the wheel is not the same as using the already existing language. That would be equivilent to saying "I'm not going to make my own drill, hammer, etc" when you use the tires, you are using someone elses end product. My point is, if someone has already done something better than you can, why waste your time? In the end, you will only wind up making an inferior product. Me, I'd rather save my time and have the superior product.
