================
Comment at: libcxx/include/__algorithm/iterator_operations.h:85-86
+  _LIBCPP_HIDE_FROM_ABI _LIBCPP_CONSTEXPR_AFTER_CXX11 static
+  // Declaring the return type is necessary for C++03.
+  // If the result of dereferencing `_Iter` is a reference type, deduce the result of calling `std::move` on it.
+  __enable_if_t<
----------------
nit: i think the comments no long apply anymore. The return type also has sfinae logic in it


================
Comment at: libcxx/include/__algorithm/iterator_operations.h:93
+
     return std::move(*std::forward<_Iter>(__i));
   }
----------------
extra nit: perhaps we don't need to forward it, because the `__deref_t` and `_move_t` are defined in terms of lvalue of `_Iter`
