Hi,

We are about to start the ruby3.1 transition in unstable. While trying to
rebuild ruby-delayed-job with ruby3.1 enabled, the build failed.

Relevant part of the build log (hopefully):
>      Failure/Error:
>        expect do
>          yaml = "--- !ruby/struct\nn: 1\n"
>          object = YAML.load(yaml)
>          expect(object).to be_kind_of(Struct)
>          expect(object.n).to eq(1)
>        end.not_to raise_error
>

The full build log is available from:

To reproduce this, you need ruby-all-dev >= 1:3.0+2.  Depending on when you
read this, this might mean installing ruby-all-dev from experimental, or ir the
transition has alraedy started in unstable, a normal build on unstable should
do it.  If you fail to reproduce, please provide a build log and diff it with
mine so that we can identify if something relevant changed in the meantime.
