<pre>Clang will reject these at the point of the function definition with
"declaration conflicts with target of using declaration already in scope":
void bar();
namespace foo { using ::bar; }
using foo::bar;
void bar() {}
and this:
void f();
using ::f;
void f() {}
The latter using declarations (if I am reading the standard correctly) are
no-ops and should not cause the definitions to be rejected.</pre>
