Things are a hot mess right now. Perhaps pulling commands.lua directly
in was a bad idea and I should have added them gradually into the
editor. However, it's nice to see multiple definitions and I don't have
that yet in the driver. We'll eventually decontruct commands.lua away
into nothing.
The major issue I'm stuck on is the representation of definitions in
memory. Each needs to be an editor buffer. I'd like to be able to get to
each by name. However, what should happen if I edit a buffer to change
the code inside it?
