That may be the case, but it may not. If the default implementation of the
traits class works fine for X, then it will compile. If the default
implementation doesn't work, it won't compile. Clearly, then, there are
situations where "smart_ptr<X>" means something different in different parts
of the code, thus violating the ODR.
