For the same reasons I am also not worried if it cannot be demonstrated, at this moment, that FC++ is the best way to solve any particular C++ problem. I am confident that it will be useful in many ways, but even if it should ultimately turn out that FC++ is never the best tool, I think accepting FC++ into boost -- with the exploration of new programming techniques and the interaction between programmers with different backgrounds which it will bring about -- would still be worthwhile.
Here we probably disagree. I see boost as a collection of libraries that intent to be used in practice. Ultimately some of them may join C++ standard. Introduction of solution for no problems does not seems to fit this. Note: I do not say that there is no problem domain, I just say that it's imperative to figure it out first, instead of telling C++ community: "Ok. Here is the library. If you find any use for it let us know" Regards, Gennadiy.
