    • More specific unit-testing of the croak location when testing `AWAIT_GET` (related to RT145249)
    • Swap all unit tests from `Test::More` to `Test2::V0`
    • Avoids test_requires on `Test::Refcount` or `Test::Fatal`
    • A more robust handling of defav during suspend/resume to try not to upset `perl -d` (RT146246)
