[libcxx-commits] [PATCH] D118963: [libc++] No longer support ranges::begin(x) when x is an array of incomplete type.

[Konstantin Varlamov via Phabricator via libcxx-commits]

var-const added inline comments.


================
Comment at: libcxx/include/__ranges/access.h:62
     template <class _Tp>
-      requires is_array_v<remove_cv_t<_Tp>>
-    [[nodiscard]] _LIBCPP_HIDE_FROM_ABI constexpr auto operator()(_Tp& __t) const noexcept
+    [[nodiscard]] _LIBCPP_HIDE_FROM_ABI constexpr auto operator()(_Tp (&__t)[]) const noexcept
+      requires (sizeof(*__t) != 0)  // Disallow incomplete element types.
----------------
Question: `end` only defines the case where the array size is known. Does the case where the size is unknown need to be handled by `end`, or does it not apply in that case?
