[Boost-users] [mpl] Instantiating a vector of factory functions

Okay, I'm a lot closer to my goal of having an automated factory of objects that are dynamically polymorphic but have their inheritance set up through static means. What I have now is something like this: // My factory template template struct Factory { Base *create() { return new Derived(); } }; // My vector of factories for the different Derived types typedef mpl::vector< Factory, Factory, Factory > MyFactories; (I actually use MPL to automatically cross and combine different classes, which is pretty cool.) Now I could create a vector of the same length with every type as a pointer to a Factory function, and with Fusion I could probably instantiate it (although I haven't got that working yet). But that still wouldn't get me what I want, which is a table of those factory functions that I can index into at run-time. Can anyone suggest a technique for doing this?
