[boost] Reimplementation of the MPL for C++11

Hi, I am currently working on a reimplementation of the MPL for C++11. Although the library is not complete yet, I would like to gauge interest for the project from the Boost community. I wanted to wait until I have resolved some core issues before posting here, but reading the [modularization] thread made it unbearable to wait any longer :-). The library is available on GitHub: github.com/ldionne/mpl11. If some people happen to be interested by the project and would like to get involved, please get in touch with me. Regards, Louis Dionne N.B.: Some design decisions will be influenced by the community (if there's interest) and I'm experimenting a lot. Don't be put off if you see something that you don't like: it might change.
