170 ///

178 /// declaration of the class template X, above. Template names can
179 /// also refer to function templates, C++0x template aliases, etc.
180 ///
181 /// Some template names are dependent. For example, consider:
182 ///
183 /// \code
184 /// template<typename MetaFun, typename T1, typename T2> struct apply2 {
185 /// typedef typename MetaFun::template apply<T1, T2>::type type;
186 /// };

190 /// specifier in the typedef. "apply" is a nested template, and can
191 /// only be understood in the context of
