+Classes/functions in the moved namespace will have new namespaces while
+references to symbols (e.g. types, functions) which are not defined in the
+changed namespace will be correctly qualified by prepending namespace
specifiers
+before them. This will try to add shortest namespace specifiers possible.
+
+When a symbol reference needs to be fully-qualified, this adds a `::` prefix to
+the namespace specifiers unless the new namespace is the global namespace. For

I understood this as fully-qualifying the namespace when necessary to refer to
the correct namespace. For example,
```c++
namespace other::foo {
a::A thing;
} // namespace other::foo
namespace foo {
a::A thing;
} // namespace foo
namespace other {
a::A thing;
struct foo {
a::A thing;
};
a::A thing2;
} // namespace other
```
becomes
```c++
namespace other::foo {
::foo::A thing;
} // namespace other::foo
namespace foo {
A thing;
} // namespace foo
namespace other {
foo::A thing;
struct foo {
::foo::A thing;
};
::foo:A thing2;
} // namespace other
```
@kwk is that understanding correct?
