================
Comment at: clang-tools-extra/clangd/unittests/TweakTests.cpp:2673
+void foo::fun() {
+  one::two::f^f();
+})cpp",
----------------
IIUC, before this patch, the using was added inside the above namespace `foo`, 
the code was still valid after applying the tweak.

There is no enclosing namespace for `foo::fun()`, so we will insert the using 
at the first top-level decl. It seems that we will break the code if the 
`one::two::ff` decl is defined in the main file (not the `test.hpp`), e.g.

```
// using one::two::ff will be inserted here, which is not valid
namespace one {
namespace two {
void ff();
}
}

namespace foo { void fun(); }
void foo::fun() {...}
```

this case was working before the patch, and now is broken after this patch. It 
is not a common case, probably ok for now.
