-/* String streams are the things fed to parsers (which can feed them
- * to a tokenizer if they want). They provide peek and next methods
- * for looking at the current character (next 'consumes' this
- * character, peek does not), and a get method for retrieving all the
- * text that was consumed since the last time get was called.
- *
- * An easy mistake to make is to let a StopIteration exception finish
- * the token stream while there are still characters pending in the
- * string stream (hitting the end of the buffer while parsing a
- * token). To make it easier to detect such errors, the stringstreams
- * throw an exception when this happens.
