clang-rename doesn't work for namespaces

[marcin-szmagara]

The official documentation advertises clang-rename as able to rename namespaces. Here is a counterexample:

Running clang-rename --qualified-name=n1 --new-name=k1 minimal-namespace-test.cpp (source file contents below)

namespace n1
{
  int x;
}

namespace n1_alias = n1;

int main()
{
  using namespace n1;
  (void)x;
  (void)n1_alias::x;
}

produces following result:

namespace k1
{
  int x;
}

namespace n1_alias = n1;

int main()
{
  using namespace n1;
  (void)x;
  (void)n1_alias::x;
}

leaving both the using directive and namespace alias declaration untouched.
