This PR replaces the
[@@must_erase_for_extraction]
attribute by the (existing)[@@erasable]
attribute. To quote the type checker source:This PR contains the immediately applicable prefix of PR #3661.
The old attribute is marked as a deprecated alias for
[@@erasable]
, so there shouldn't be any failures. Unless you turn warnings into errors, as Inria projects do (remember to ping TWal after merging).
