…ed classes Implements the struct type `std::destroying_delete_t`, variable `std::destroying_delete`, and feature test macro `__cpp_lib_destroying_delete` in C++20 mode with a compiler that defines `__cpp_impl_destroying_delete`.
... and annotate to update when VS 2019 16.7p1 releases with support in MSVC.

There was a problem hiding this comment.
FYI, I pushed some updates:
- clang-format
- Feature-test macro tests for
__cpp_impl_destroying_deleteand__cpp_lib_destroying_delete(variously enabled until we update our toolset compiler) - Enabled the libc++ destroying delete test when compiling with clang to get some library test coverage
I've also filed #693 to cleanup the messy partially-enabled bits after VS 2019 16.7p1 ships.
EDIT: (I'd port these changes to your internal PR, @joemmett, but I can't find one??!?)

The transition comments mention 16.7 preview 1, but this doesn't seems to work on the public release of 16.7 preview 1 |

It should work when compiling with Clang - the tests work, anyway. The compiler support for destroying delete in MSVC was delayed to 16.7p2 as indicated in #693. |
