-   * A type that is sometimes used for template tricks. For example, in some
-   * situations one would like to do this:
-   *
-   * @code
-   *   template <int dim>
-   *   class X
-   *   {
-   *     // do something on subdim-dimensional sub-objects of the big
-   *     // dim-dimensional thing (for example on vertices/lines/quads of
-   *     // cells):
-   *     template <int subdim> void f();
-   *   };
-   *
-   *   template <int dim>
-   *   template <>
-   *   void X<dim>::f<0> ()
-   *   {
-   *     ...operate on the vertices of a cell...
-   *   }
-   *
-   *   template <int dim, int subdim> void g(X<dim> &x)
-   *   {
-   *     x.f<subdim> ();
-   *   }
-   * @endcode
-   *
-   * The problem is: the language doesn't allow us to specialize
-   * <code>X::f()</code> without specializing the outer class first. One of
-   * the common tricks is therefore to use something like this:
-   *
-   * @code
-   *   template <int N>
-   *   struct int2type
-   *   {};
-   *
-   *   template <int dim>
-   *   class X
-   *   {
-   *     // do something on subdim-dimensional sub-objects of the big
-   *     // dim-dimensional thing (for example on vertices/lines/quads of
-   *     // cells):
-   *     void f(int2type<0>);
-   *     void f(int2type<1>);
-   *     void f(int2type<2>);
-   *     void f(int2type<3>);
-   *   };
-   *
-   *   template <int dim>
-   *   void X<dim>::f (int2type<0>)
-   *   {
-   *     ...operate on the vertices of a cell...
-   *   }
-   *
-   *   template <int dim>
-   *   void X<dim>::f (int2type<1>)
-   *   {
-   *     ...operate on the lines of a cell...
-   *   }
-   *
-   *   template <int dim, int subdim>
-   *   void g(X<dim> &x)
-   *   {
-   *     x.f (int2type<subdim>());
-   *   }
-   * @endcode
-   *
-   * Note that we have replaced specialization of <code>X::f()</code> by
-   * overloading, but that from inside the function <code>g()</code>, we can
-   * still select which of the different <code>X::f()</code> we want based on
-   * the <code>subdim</code> template argument.
-   *
-   * @deprecated Use std::integral_constant<int, N> instead.
