What was that comment in "Field of Dreams"? "Build it and they will come"? It might take a while, but I think it'll happen. I think the idea of building a serious boost math library is great! I am more of a mathematician than a C++ programmer, and I think both C++ and boost are absolutely wonderful. C++ allows me to implement in code the same principles and techniques of abstraction that I use in my (completely pure) research. All of boost is built using these same principles; I found it completely miraculous that I could find a software library that is completely compatible with the same philosophy that I use to do mathematics and write software. If boost can package crucial mathematical algorithms and functions in a suitable abstract framework, it would be great.
