Thanks for the kind words, I like matchers a lot too. Props to Rob for
putting them into testtools in the first place, and Michael for adding
MatchesStructure.

Nice. Inspired me to hack up
<https://code.launchpad.net/~jml/testtools/structure-from-dict/+merge/68409>,
which would allow you to write this instead::

self.assertThat(
    copy_job, MatchesStructure.byEquality(
        package_name=source_name,
        package_version=version,
        target_archive=target_archive,
        source_archive=source_archive,
        target_distroseries=to_series,
        target_pocket=to_pocket,
        include_binaries=False,
        copy_policy=PackageCopyPolicy.INSECURE))
