Not necessarily. There's quite a lot of need for an automatically
*persistent* data structure like this -- i.e. one that survives between
different runs of a program -- right now. Full-blown databases are
overkill for many more-modest purposes, especially SQL databases.

I realize that this could be done with serialization and such, and that
would make sense if you needed to use the data on different
architectures or operating systems. But if you just need to store, for
example, the unfinished results of a long calculation while the user
shuts down the program, and pick them up when the program is resumed,
this would be ideal.
