> There are namespaces, you just don't see them. That's why there's python and python3, cmake and cmake2 (IIRC) etc. That's a versioning issue, that would happen with namespaces too. You'll have to disambiguate somehow and if a version number is the natural way, then that's the natural way regardless of if a single name or namespaced. Keeping the next incompatible version as a separate thing (eg python vs python3, instead of continuing python but with semvers saying that 3.0 breaks 2.x compatibility) is actually a good idea. It leads to fragmentation, sure, but it makes dealing with the different versions easier IMHO and incompatible versions may as well be totally different things anyway. > With functions it's worse. In a flat namespace you will inevitably run into a problem of two people coming up with the same name. Yes, completely agree!
