Nanorange failed with error C2607 on MSVC

[QuellaZhang]

Hi all,

NanoRange assert failed on upcoming version of MSVC: F:\gitP\tcbrindle\nanorange\test\test_concepts.cpp(183): error C2607: static assertion failed

The failing line is:

static_assert(rng::default_initializable);

which eventually reaches:

template
inline constexpr bool
is_default_initializable<T, std::void_t<decltype(::new T)>> = true;

'::new const int' is not valid as you cannot default initialize a 'const int'.

Thanks for the notification, I think I reported this bug in MSVC so it's good to see it's been fixed (and also that this comment seemed to work!).

Could you tell me the value of _MSC_VER in the fixed version?

Yes, you reported it on DevCom. I saw Jon Caves fixing a very similar bug and convinced him to get this one as well so our default_initializable implementations will work. 🎉

1929, which will be the _MSC_VER for both 16.10 and 16.11. This will probably be in 16.10p3.

Thanks Casey!
