I've looked at all the responses here which suggest that such a library wouldn't be a great idea. None of them convince me. Every boost library has competition - this is not a bad thing. Boost libraries tend to work better with other boost libraries and the standard library. Boost library tend to be of higher quality than other libraries In the future we will see more libraries of narrower application - because we've already made libraries for the wider applications. If you make such a library, and it's of high quality, I see no reason why boost wouldn't accept it.
