Some comments inline, other than that, two issues with this pull request:
- A lot of whitespace reformatting. We explicitly ask not to do this.
Some IDEs do it automatically, but you can deactivate it. It makes diffs
dangerously convoluted.
- Tuple0 can be treated as a singleton, since it has no state. Any reason
not to do this?
