The distributed version of nose looks like this:

    def _set_tests(self, tests):
        self._precache = []
        is_suite = isinstance(tests, unittest.TestSuite)
        if isinstance(tests, collections.Callable) and not is_suite:

The same code in this repository is different:

According to git history the above has not changed in 15 years.

As a consequence the distributed version is not Python 3.10 compatible, and I don't know how to contribute a fix because it is apparently already fixed.

Is there any plans for a new version that contains the correct code?
