Yes, and that's the direction I'm planning to explore.
I'm just now setting up to try out such suggestions.
You may find that post-hoc filtering with "|" is not going to allow you to avoid traversing into subdirectories that will ultimately be filtered out.
This would be problematic IMO.
On the other hand, maybe it's possible to do something with expression templates that saves you from that problem.
Seems extreamly complicated. -Thorsten
