Forward-declaring class templates is as easy as a normal class declaration: template class X; It is also possible to provide forward declarations for specializations of those class templates: template class X; template <> class X; If no user-declared prospective destructor is provided for class T, the compiler will always declare one (see below), and the implicitly declared prospective destructor is also the destructor for T .
