> But it doesn't give one when the cast is in a loop condition. That is weird. I believe that the justification for that is that you'll often want to do e.g. while (node) { node.val += 3; node = node->next; } Implicit conversion of a type into a bool is pretty useful here, or for e.g. while (std::cin >> x >> y) { ... }
