Both strings and lists can be seen as ordered sequences of MOO values. In the
case of strings, each is a sequence of single-character strings; that is, one
can view the string "bar" as a sequence of the strings "b",
"a", and "r". MOO allows you to refer to the elements of lists
and strings by number, by the index of that element in the list or
string. The first element in a list or string has index 1, the second has
index 2, and so on.
