Hi @greghogan, thank you for the PR.
I didn't spot anything that needs fixing, but I'm wondering what's the
motivation to add these interfaces. I see how `toVerboseString()` is useful,
but not really why `AnalyticResult` is needed. Also, why introduce
`UnaryResult`, `BinaryResult`, and `TertiaryResult` instead of simply using
tuple types?
I also see that this PR contains no changes to the docs and that the
current 1.3-SNAPSHOT docs already reflect the changes of this PR. What am I
missing here?
