Using declarations to 'import' symbols from base classes are legal only at
class definition scope, not member function scope. You can use using
declarations at function scope to import from other namespaces, that's
perfectly legal:

namespace A
{ int a; }

struct Foo {
  void Bar(void)
  {
    using A::a;
    a = 5;
  }
};

I agree that the proposed code should not compile.
