The structure of the generated JSON is meant to be close to idiomatic JSON. This means:

• Enumerations are converted to JSON strings.

• Record fields become JSON keys.

• Data types with one unlabeled field convert to just that field.

• Data types with multiple unlabeled fields become arrays.

• Multiple constructors are represented by keys.

• 'Maybe' values are either an absent key, or the value.

See tests/Main.hs for more examples.
