The one mistake the beginners commonly make is to think that they need
to declare something a persistent class AND put it in a btree.  You
don't need to do that; a persistent class in fact generates one (plus
one for each index) btree, but those should not be visible to the user
of the class.

Things like "mapclass" and "get-instances-by-range" provide a more
abstract interface than the btree interface.

Of course, you may be explicitly managing a btree, and that may be a
completely appropriate thing to do, depending on your application.
