Sequence objects typically may be compared to other objects with the same sequence

type. The comparison uses *lexicographical* ordering: first the first two

items are compared, and if they differ this determines the outcome of the

comparison; if they are equal, the next two items are compared, and so on, until

either sequence is exhausted. If two items to be compared are themselves

sequences of the same type, the lexicographical comparison is carried out

recursively. If all items of two sequences compare equal, the sequences are

considered equal. If one sequence is an initial sub-sequence of the other, the

shorter sequence is the smaller (lesser) one. Lexicographical ordering for

strings uses the Unicode code point number to order individual characters.
