+    // Note:
+    // The weird definition as a variable seems to exploit a glitch in Doxygen
+    // which makes the macro appear in the related objects of Struct (as we
+    // want it to).
+
+    //! Defines members of a structure, while at the same time
+    //! modeling `Struct`.
+    //! @ingroup group-Struct
+    //!
+    //! Using this macro in the body of a user-defined type will define the
+    //! given members inside that type, and will also provide a model of the
+    //! `Struct` concept for that user-defined type. This macro is often the
+    //! easiest way to define a model of the `Struct` concept.
+    //!
+    //! @note
+    //! This macro only works if the tag of the user-defined type `T` is `T`
+    //! itself. This is the case unless you specifically asked for something
+    //! different; see `tag_of`'s documentation.
+    //!
+    //!
+    //! Example
+    //! -------
+    //! @include example/define_struct.cpp
