PEP-44, you can't make your own tuple type. The typing that's applied to tuples is actually hard coded in the MyPys source. I'm doing this just so my editor is more approachable to me on auto complete. It doesn't work with violence. And I have a new approach that I worked out with some other people for violence type stuff where we won't need a plugin. But first of all, we do have a my pie plugin where you are able to use annotations like name colon string and it will automatically work them into the correct kind of thing to be recognized at the query level.
