Travis Vitek commented on STDCXX-979:
-------------------------------------
Should we not provide a definition of {{nullptr_t}} and {{nullptr}} for those
systems that don't provide it natively?
> __rw_is_scalar or is_scalar need to take std::nullptr_t into account
> --------------------------------------------------------------------

> The standard requires that {{std::is_scalar<std::nullptr_t>::value}} evaluate
> to true. The current implementation doesn't consider the {{std::nullptr_t}}
> type because it is not implemented yet.
