More generally, when inside the scope of a derived class, a class template base name may be used without being qualified by its template parameter list. Often times, people will attempt to shorten their code (in a derived class) by using, for example: <code>typedef Base<T> MyBase</code> This is, however, completely redundant. @ASk: Base::print and Base<T>::print will refer to the same instantiation.

using Base::print;

and then the name will be made available.
