I have similar issues with bsddb. Here, there are Factory functions like
"DBEnv" or "DB", creating "DBEnv" and "DB" class instances. Note the
name aliasing.

I don't understand why these functions exist. It causes a few problems,
like being unable to subclass the bsddb classes, for example.

For future bsddb4.6.4 (Late october, I think) I plan to remove the
Factory functions, exporting the classes directly, and allowing
subclassing. The code should be 100% compatible.

Any opinion?
