as long as there remains a way to run destructors with heap-based lifetimes. TLS works this way. taskgroups do too, though could be made not to with a bunch of hoop-jumping.

@astavonin I believe that we agreed that you can get resource functionality by implementing a special, wired in trait that has one method, drop. The thing blocking this was coherence, but now we do have coherence. This special trait is not implemented yet AFAIK, but it will be.

BTW, the issue for adding the special wired-in trait for drop is #3061.
