How to implement a compile-time meta-container in C++ (b.atch.se)

A detailed post that shows how to implement a stateful meta-container that is usable where a constant-expression is required, effectively making it possible to store away different states during compilation of a program. The approach enables the world of meta-template programming to closely follow the semantics of imperative programming.
