Since there's no general persistence mechanism in BFG, there's no general way
query any persistent storage. In order to do this in a application that uses
ZODB, you'd need to write a function that traverses your object graph. But
since there's no such thing as a "generic" object graph, this function needs to
be something custom for each graph.
