Enelar / dynamic_construction_choose.cpp
Created March 20, 2014 10:30
With this gist you could get array of object overloaded methods(lambda+circuit) by its names. For simple example i support only constructors, but i hope you realize `what you should change` to get every function you want.
#include <functional>
#include <iostream>
using namespace std;
struct objT
{
};
struct a : objT
