<P>Why would you want to use a hashing class instead of the
&quot;normal&quot; implementations? Matt Austern writes:
<BLOCKQUOTE><EM>[W]ith a well chosen hash function, hash tables
generally provide much better average-case performance than binary
search trees, and much worse worst-case performance. So if your
implementation has hash_map, if you don't mind using nonstandard
components, and if you aren't scared about the possibility of
pathological cases, you'll probably get better performance from
hash_map.</EM></BLOCKQUOTE>
