c++: std::vector of std::function with arbitrary signatures

Question

Is it possible to create an std::vector that can hold an std::function with any signature? (The function arguments would all be pre-bound.)

Answer 1

This should work:

#include 
#include 
#include 

void hello() { std::cout << "Hello\n"; }
void hello2(const char * name) { std::cout << "Hello " << name << '\n'; }

int main()
{

    std::vector> v;
    v.push_back(hello);
    v.push_back(std::bind(hello2, "tim"));
    v[0]();
    v[1]();
}

How are you doing it?
