This can indeed be a good solution. Given that perl will reliably call DESTROY when an object goes out of scope, this could ensure that whatever the object holds will be cleaned up. It is a bit more code to write as we need to call the function, but might be reasonable.
sub test_something { my $tempdir = create_tempdir(); # ... }

I don't know where the idea came from that in Python people include the tests in the main code. Maybe that was the case 10 years ago, but these days the standard is that tests are in separate files called test_SOMETHING.py.

      I am not sure what closure are you talking about here, but the best would be if you could show a code snippet how you think it would be used in a test? And yes, it would be nice to avoid the linked problem.
        > show a code snippet how you think it would be used in a test?

        pseudocode, because I don't know your project sufficiently well

        { my $fixture_A = temdir(); # fixture in closure sub test1 ($fixture_B) { # no need to repeat A # uses fixture A and B } sub test2 ($fixture_C) { # no need to repeat A # uses fixture A and B } }

        NB: I use "closure" in the original sense, it's the hull with "enclosed vars" not the enclosed sub.
