Comment(by danieljames):

 From the [http://article.gmane.org/gmane.comp.lib.boost.documentation/1055

 original email] with the formatting corrected:

 John:

   Just another data point: escaping to !BoostBook from within code doesn't
   work unless the escape is inside a macro:

   {{{
   template <class T>
   struct function_traits
   {
     static const std::size_t arity = __below;
     typedef __below result_type;
     typedef __below '''arg<replaceable>N</replaceable>_type''';
   };
   }}}

   Does '''not''' process the escape, whereas:

   {{{
   [def __argN '''arg<replaceable>N</replaceable>_type''']
   template <class T>
   struct function_traits
   {
     static const std::size_t arity = __below;
     typedef __below result_type;
     typedef __below __argN;
   };
   }}}

   Does process the escape.  Took me a while to figure this out :-(
