See https://github.com/python/typing/issues/518 for context. The typing documentation for 3.6.4rc1 states: > typing.io ... defines the generic type IO[AnyStr] and aliases TextIO and BinaryIO for respectively IO[str] and IO[bytes]. In the current implementation TextIO and BinaryIO are not aliases, but instead derived from IO. This means that values of type IO[...], and especially IO[Any] can not be assigned where TextIO or BinaryIO is expected.

This doc bug should be fixed before 3.6.4 final goes out.
