As suggested via @jezdez in #334.
In case you missed it, the tests failed
@jezdez - the test failures are what I didn't understand: how to access _default_manager of TagBase which is an abstract base class.
Got the .__class__ method from IRC logs last week. Still 1 test failure I need to debug.
for #333 - access _default_manager via TagBase class
Updated; everything should be fixed now.
Any chance to get a merge & release for this anytime soon?
Released 0.16.4 with this change
