I.e. by allowing you to define the unexepcted you could for

enum JSONError {
invalidKey, notString, notNumber
}
auto a = parse(jsonData);
a.getAsString("key").match!(
(string value) => // yay
(JSONError error) => // small domain of what went wrong
);
I agree that this is useful, but why not just return a naked
`SumType!(string, JSONError)` in that case? Is there some
additional value added by the `Expect` wrapper that I'm not
seeing?
