    -- ^ Constructor names won't be encoded. Instead only the contents of the
    -- constructor will be encoded as if the type had a single constructor. JSON
    -- encodings have to be disjoint for decoding to work properly.
    --
    -- When decoding, constructors are tried in the order of definition. If some
    -- encodings overlap, the first one defined will succeed.
    --
    -- /Note:/ Nullary constructors are encoded as strings (using
    -- 'constructorTagModifier'). Having a nullary constructor alongside a
    -- single field constructor that encodes to a string leads to ambiguity.
    --
    -- /Note:/ Only the last error is kept when decoding, so in the case of
    -- malformed JSON, only an error for the last constructor will be reported.

    -- ^ A constructor will be encoded to an object with a single

    -- ^ A constructor will be encoded to a 2-element array where the
    -- first element is the tag of the constructor (modified by the
    -- 'constructorTagModifier') and the second element the encoded
