Cool, so actually T::B::Counter and T::B::Run are not singletons and Test::Builder is. > > That will lose the default level management. But I don't really understand > > the default level thing.

So: 1 - What does it means for Test::D to have a default level of 2? Does it mean that all calls on the T::B object have to originate from exactly 2 levels of calls into Test::D? If so, what can I do if some are from depth 3 or 1? 2 - What happens if Test::C::do_multiple_tests() calls Test::D::some_test()? The correct level is now Test::C's default level + Test::D's default level - 1 (or + 1 depending on the exact definition of level). Unless less Test::C is testing Test::D in which case... also Test::Builder may not even know how to find out what Test::C's default level is (it can't necessarily see Test::C's Test::Builder object and in fact Test::C may have created more than 1).
