General methods of use of Boost::any

#include <boost/any.hpp>
.
05.typedef std::list<boost::any> List_any;
.
07.//key part: Ability to store arbitrary types of objects
08.void fill_list (list_any& la)
09.{
La.push_back (1000);//Store constant
La.push_back (std::string ("This is an example"));//Store string object; note La.push_back ("Dyunze") error, due to being the wrong string array
