{This is a second attempt to post} With a help of boost::dynamic_any::call operation (not yet implemented) it's possible to use boost::dynamic_any::any instead of Boost.Function. Though this new solution is less specialized and probably slower then Boost.Function it has one advantage demonstrated in the example below:
typedef boost::dynamic_any< boost::mpl::list< boost::dynamic_any::call<void (int &)>, boost::dynamic_any::call<void (double &)> > > flexible_function; // 2 in 1! int main() { flexible_function f; f = ++_1; // increment for int and double int i = 2; f(i); // ++i double d = 3; f(d); // ++d } -- Alexander Nasonov Remove - m y c o p from my e-mail address for timely response _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
