--- Type class with two conversion operations between values and their
--- JSON representation. Since a JSON value might not contain
--- a correct representation of a standard value, the operation
--- `fromJSON` returns a `Maybe` value.
--- The additional operations on value lists are used for a better
--- JSON conversion of strings.
