Having spent several hours yesterday pairing with a new user, we copied a lot of examples from our docs, and in every case, we had to paste in our namespace ApprovalTests:: - it got very old, very quickly - and I ended up agreeing with this:

Please, I implore you, in the name of all that is good, do NOT use using namespace in your examples for your library.

It makes it impossible to figure out where things come from when we are studying the examples.

At least for example and test code that is included in snippets, I would now really like to ban using namespace ApprovalTests; in any of our source files where there is a snippet defined! And also, add a check to fail the build if such a usage slips back in, in future...
