I have tried to mark those signature tests with unittest.expectedFailure but then the test fails on "UNEXPECTED SUCCESS", very strange.

I have tried to mess with defining __text_signature__ but I'm guessing that I'm doing something wrong because it completely ignores it. I would appreciate any suggestion that you have:)
