Again, it's about the use case. For small fields you probably don't
have to worry about reading inefficiencies, so use delimiters. For
large fields use fixed-length or length-prefixed, for the reasons I
mentioned. These two approaches are both easy to write, one is just
faster to seek to the nth item, and the other is more compact,
respectively.
