Dear Boost, It has been a while since I've given news about my GSoC project, Boost.Hana[1]. Things are going very well and I uploaded the library to the Boost Incubator. I think it is time to push the library forward for review. As the author, I know everything that's left to be done and polished before I can be fully satisfied. Still, I believe the library is worthwhile in its current state as it implements a superset of the functionality found in the Boost.MPL and Boost.Fusion. I also think the library will benefit greatly from a larger user base and more feedback. Here are some caveats: - The library requires a full C++14 compiler, so only Clang 3.5 can compile the unit tests right now. However, compilers will eventually catch up. Also, pushing cutting edge libraries forward might motivate compilers to support C++14 ASAP, which is probably a good thing. - The library is not fully stable yet, so interface changes are to be expected. I don't see this as a problem as long as this is documented, especially since I expect Hana to be used mostly for toying around for at least a while. I could be mistaken. So unless someone thinks the library isn't ready or would get rejected right away in its current state for reason X, I am requesting a formal review for Boost.Hana.
