212 * collection of appended and prepended terms is done lazily, making long
213 * operations that involve many appends very inexpensive. In addition
214 * internal ref-counting means that if you pass strings around between
215 * functions there's almost no overhead in time or memory since a reference
216 * is created and no data is actually copied. This also means that you
217 * never need to put any BasicString into a ref-counting container class.
