[libcxx-commits] [PATCH] D81954: Remove the try/catch codepath if `swap` is `noexcept`.

Comment at: libcxx/include/variant:1070
+          __all<(is_nothrow_move_constructible_v<_Types> &&
+                 is_nothrow_swappable_v<_Types>)...>::value;
+#endif
----------------
Why is the `is_nothrow_swappable_v` requirement checked here?
The code below is just calling __generic_construct and __move_nothrow, neither of which seem to call swap().
