An overview of motivation behind Torque and some of its principles
can be found here: https://bit.ly/2qAI5Ep

Note that there is quite a bit of work left to do in order to get
Torque production-ready for any non-trivial amount of code, but
landing the prototype as-is will allow for much faster iteration.

Bugs will be filed for all of the big-ticket items that are not
landing blockers but called out in this patch as important to fix.
