Whenever I hear about some useful proposal for C++ being shot down because “this would be a breaking change” I gnash my teeth in frustration, but then remember the python 3 debacle and calm down. In fact a lot of my frustration with C++ evolution is due to the committee’s experience of having made a couple of bad decisions that had to be undone (like auto_ptr), or which are unrepairsble (overconstrained unordered_map). Which is a great example of why you shouldn’t have someone like me on the committee!
