Let's definitely move to type annotations, since they are much more likely to be correct due to validation by MyPy.

To start, we'll need to revise the Twisted coding standard [1] to permit type annotations instead of @type lines in the docstring. I think that we should suggest, but not require, annotation syntax to start. I filed a ticket [2] for this.
