Java can potentially have the same problem. But because everyone uses an IDE and because it's rarely really an issue, everyone will simply import `Baz` rather than worry about the Foo::Baz and Bat::Baz collision. It does happen in java code, but I can't stress how infrequently it's actually a problem.

In java, I rarely pay attention to the `import` section (and I know most devs at my company).

You can look up `using namespace std;` in google and you'll find a lot of articles saying it's a bad practice in C++. Everyone recommends writing the full `std::cout` rather than `cout`.

I do think it’s down to personal preference. With the fully qualified names, I can look at the screen and follow the flow without having to mouse over the various names in play. For that matter, I could print it out if I wanted to and still have all the information.

I don’t think you’re objectively wrong. It’s more that we have different approaches to managing the complexity when it gets hairy.
