It was there to show how it should be used in user code, and testing.
Swizzle is not just a rvalue operation, there is also a lvalue part to it  
which plays a bit differently (hence, swizzleR and swizzleL).
We could take care of it with an overload but D doesn't act quite like  
what i expected (like C++), i don't understand why it won't differentiate  
"fun()" from "fun() const".
