Implementing the C++ standard library is both similar to writing a boost library and yet quite different. In this talk, I'll lead off with what are some of the challenges that a standard library implementor faces, as well as the advantages that one has.
Then, I'll apply the principles to the task of maintaining/improving a boost library, and note where the similarities and differences lie. Many of the motivations (stability, portability, etc) are almost exactly the same.
I'll also talk about balancing the needs of different "customers"; people who use the standard library in different ways, and what you can do to keep all (most?) of them happy.
