Yup, that's the topic I'm interested in.

IMO the backend should be expanded to handle this stuff. In fact I had
actual plans to add the recursive stuff but have not even found enough time
to dig into the source code. 

For those who don't know, I made my Ph.D. in deductive database systems
which is mostly about recursive queries and transitive closures.
