The offset given to @racket[get-token] can be added
to the position of the input port to obtain absolute coordinates within a
text stream. The extra two results are
@itemize[@item{a new mode;
@itemize[@item{a backup distance;
The backup distance returned by @racket[get-token] indicates the
maximum number of characters to back up (counting from the start of the
token) and for re-parsing after a change to the editor within the token's
region.}
@item{a new mode;
The mode argument allows @racket[get-token] to communicate
information from earlier parsing to later. When @racket[get-token] is
called for the beginning on a stream, the mode argument is @racket[#f];
