Re: Compile time container, run-time execution.

template<class Derived>
struct auto_register
{
    //singleton that hold existing Derived
    static list<Derived*>& container()
    {static list<Derived*> obj_list;return obj_list;}
   auto_register()
   {
        container().push_back(static_cast<Derived*>(this));
   }
   ~auto_register()
   {
        container().erase(static_cast<Derived*>(this));
   }
};
And then:
class Foo:auto_register<Foo>
{
};
