--- Comment #5 from Jonathan Wakely  ---
Maybe we could take this opportunity to get rid of most of the __8 namespaces
and only have std::__8 and __gnu_cxx::__8, rather than std::__8 and numerous
std::xxx::__8 namespaces.

That would simplify the code, as the correct placement of
__GLIBCXX_BEGIN_NAMESPACE_VERSION and _GLIBCXX_END_NAMESPACE_VERSION is a
constant source of bugs.

--- Comment #4 from Jonathan Wakely  ---
We have this structure in libstdc++:

namespace std
{
  inline namespace __8 { }

  inline namespace literals {
inline namespace chrono_literals { inline namespace __8 { } }
inline namespace complex_literals { inline namespace __8 { } }
inline namespace string_literals { inline namespace __8 { } }
inline namespace string_view_literals { inline namespace __8 { } }
  }
}

The innermost __8 namespaces conflict with std::__8 so we'll need to remove
them. Maybe we can change to:

namespace std
{
  inline namespace __8 {
inline namespace literals {
  inline namespace chrono_literals { }
  inline namespace complex_literals { }
  inline namespace string_literals { }
  inline namespace string_view_literals { }
}
  }
}
