-Subject: [PATCH] Work around broken integration with latest libc++. (#1635)
-
-* Work around broken integration with latest libc++.
-
-In newer versions of libc++, the base template of std::iterator_traits
-provides a member typedef called __primary_template which is an alias
-to the std::iterator_traits specialization itself. This fix works with
-both the old version of libc++ and the new one.
-
-Fixes issue #1633.
-
-* Fix is_std_iterator_traits_specialized_v on MSVC
-
-It used to pretend that std::iterator_traits<T*> is a user-defined
-specialization, which isn't the case. This is due to MSVC's
-iterator_traits<T*> specialization not posing as the base template.
