 Description   

This task involves adding new functionality to allow for implicit subquery support, rather than the existing requirement for subqueries, which require you to understand how tables should be joined, rather than relying on the system to do this work for you.

The work itself will be tied into the PQL work, but may be raised as a separate PR against the core code, as it's useful for both existing query facilities, and the future query facilities. So whether this patch belongs in the prototype branch, or a new one is yet to be decided.
