Does it make sense to use PyTuple_CheckExact instead of PyTuple_Check? With PyTuple_Check we can pass to __type_params__ subclass of tuple. May it break something?

We don't really use the __type_params__ in the interpreter, so there's low risk. The other attributes also allow subclasses (e.g. check func_set_defaults and func_set_name).
