issubclass() not as documented

[Skaperen]

I don't know why you'd look in a PDF for tests - by "tests", I mean code that executes the functions to make sure their behaviour is correct (in this case, those are unit tests). I haven't seen how the standard library code is organised, but it should be quite easy to find the tests in the repo.

so basically, this comes down to suggesting that i look a source code to see what it really does? then, what's the point of having documentation?
