That's a fair call, I just would imagined mnesia would provide some
syntactic sugar to fill out the value in the key-value pair with some
kind of dummy value.

Then again, the reason why I am using mnesia just to maintain a tree
index could be questioned.

The reason why I'm doing this is for easy maintenance in a clustered scenario.

Maybe their are other ways to acheive the same goal?
