+Subject: [PATCH] enum: explicitely set enum.__str__
+
+Python 3.8 has removed the int.__str__ implementation. So we don't fall
+back to object.__str__ and thus enum.__repr__ set __str__ to int.__repr__
+instead. This gives us the same behaviour with all python versions.
+
+See https://github.com/python/cpython/commit/96aeaec64738b730
