<pre>Consider:
namespace A {
inline namespace B { template<class> struct C; }
template<class> struct C;
template<> struct C<int>{};
}
Name lookup for `C` is obviously ambiguous, but the resulting error message
doesn't mention that at all:
prog.cc:4:23: error: explicit specialization of non-template struct 'C'
template<> struct C<int>{};
^~~~~~
prog.cc:4:23: error: redefinition of 'C' as different kind of symbol
prog.cc:3:28: note: previous definition is here
template<class> struct C;
^
2 errors generated.</pre>
