I would use something weaker, and I wouldn't use objects
either. To me, this is essentially a dynamic scenario,
so the data type should be dynamic. For example:

	type field_t = [
	| `Title of string
	| `Intro of string
	| `Body of string
	| `Field of string * string
	]

	type story_t = field_t list
