OCLOperators ExecuteQueryPlan

From MDrivenWiki

When you have a collection of objects you do not know the fetch status of and you are going to follow associations or derive stuff that follows associations, it is a good idea to ask MDriven to ExecuteQueryPlan.

It enters "fact-finder-mode", running your expressions in the ViewModel in a harness - looking at what data WOULD be fetched - then it fetches that data and runs the fact-finder again. This way, we can avoid 1000 single fetches and end up with 2-3 large fetches instead.
