Dependency injection in C++

Question

This is also a question that I asked in a comment in one of Miško Hevery\'s google talks that was dealing with dependency injection but it got buried in the comments.

Answer 1

I've recently been bitten by the DI bug. I think it solves a lot of complexity problems, especially the automated part. I've written a prototype which lets you use DI in a pretty C++ way, or at least I think so. You can take a look at the code example here: http://codepad.org/GpOujZ79

The things that are obviously missing: no scoping, no binding of interface to implementation. The latter is pretty easy to solve, the former, I've no idea.

I'd be grateful if anyone here has an opinion on the code.
