Another dict method...

Sorry.  My confusion.  I sometimes use bsddb.btopen like a persistent dict,
and it's .next does return in sorted order, so I transferred the thinking to
what dict.next might do.  Looking closer, I see that not even
bsddb.hashopen.next returns keys in sorted order.

I'll just remember that next means another and doesn't imply ordering.
<wink>
