Range-v3 seems to be solving a different problem. It seems to be introducing support for Pythonesque features like type-checking and list-comprehension. However, the algorithms that are documented still use first/last iterators (http://en.cppreference.com/w/cpp/experimental/ranges/algorithm/sort http://en.cppreference.com/w/cpp/experimental/ranges/algorit...). There seems to be a set of basic range class definitions and there seems to be a View class, but I'm not sure if they interact to provide the same type of generic slice definition that I've developed here. Perhaps I am missing something though, could you expand a little on the specific part of Range-v3 that you are thinking of?
