-Pointers are generally preferred to references. References should be used for
-optimizing the passing in of parameters and for returning from accessor
-operators (e.g. ```T &Vector::operator[](size_t)```).

-A non-const reference is generally used because the parameter value is changed
-in the function, but it will look like it was passed in by value where it is
-called and thus not subject to change.
-The reference operator makes it clear to the caller that the value can and
-likely will change.
