[libcxx-commits] [PATCH] D55840: P0722R3: Implement library support for destroying delete

[Eric Fiselier via Phabricator via libcxx-commits]

EricWF added a comment.

Question:

In C++20 we should declare `destroying_delete_t`, even if `__cpp_impl_destroying_delete` isn't defined.
But in that case should be define `__cpp_lib_destroying_delete`? The library has the type, but users
can't actually perform destroying delete.

Since `__cpp_impl_destroyng_delete` isn't for users, but `__cpp_lib_destroying_delete` is, then I don't think we should define it unless the compiler actually provides the language feature.
