I've written a macro (the implementation is attached) for generating a function object for using overloaded functions with generic code such as the STL algorithms and boost::bind. A simple example of it's use: void foo(int); void foo(char*); GENERATE_OVERLOADED(void, foo); int main() { int values[] = { 1, 2, 3, 4 }; std::for_each(values, values+4, foo_overloaded); } GENERATE_OVERLOADED (yes, the naming is pretty bad) creates an object called which contains overloaded calls to operator() which forward to the named functions. Something like: struct foo_overloaded_type { void operator() const { return foo(); } template <class T1> void operator(T1 const& p1) const { return foo(p1); } template <class T1, class T2> void operator(T1 const& p1, T2 const& p2) const { return foo(p1, p2); } // etc. } foo_overloaded; The main advantage is that you don't have to select the desired overload. It can also be useful when different calls will have different argument types such as iterating over a tuple in fusion (I guess you could call it a visitor). Any comments on this? Would anyone else find this useful? Also, has anyone done something similar? I'd be surprised if no one has, I always feel like I'm missing something when I'm doing this kind of thing. The implementation is lacking in several ways - it doesn't work for non-const references, the return type is fixed, needs to deal with member functions, namespace issues and so on. I suppose, it could also be better integrated with bind, lambda or pheonix. Daniel
