I got this testcase slightly wrong, the `template<>` is handled via `VisitDeclaratorDecl`, but it can have arguments as well:

  template <class T>
  class A {
     template <class U> void foo(U a) { }
     template<> void foo<int>(int a) { }  // note the <int>
  };

which is what requires handling `ClassScopeFunctionSpecializationDecl::getTemplateArgsAsWritten()`
