I would argue that _everything_ can be represented by two types: strings and
lists of string; Everything else can be represented either in a string or a
list of strings (with the possible exception of dictionaries, but I won't go
there.)  Since these two types are so fundamental I'd argue they are both
worthy of inclusion.
