Stream marks are intended to be used in

situations where you need to read ahead a little to see what's in

the stream. Often this is most easily done by invoking some

general parser. If the stream is of the type handled by the

|
parse, it just chugs along happily. If the stream is not of
|
|
that type, the parser should toss an exception when it fails.
|
|
If this happens within readlimit bytes, it allows the outer
|
|
code to reset the stream and try another parser.</div>
