--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Yes, we want to special case the inline namespaces std::__cxx11 and std::_V2 so
that they only show their contents as std::xxx not std::_V2::xxx. Or maybe
automatically elide any inline namespace under std, so that we show
std::experimental::source_location not
std::experimental::fundamentals_v2::source_location. The point of an inline
namespace is that you don't need to use it to refer to the type, the type can
be named as though it was declared in the enclosing namespace.

Clang's libc++ std::string is really std::__v1::string but it hides the inline
namespace __v1 from you.
