Overpass API: Return only non-closed ways

Is there a way to limit results of an Overpass API query to only non-closed ways?

By non-closed ways I mean ways where every node of the way’s definition occurs only once.

I would need such a query for http://tools.geofabrik.de/osmi/?view=addresses . See https://github.com/ltog/osmi-addresses/issues/70 .

I have no solution for this, but try to ask

http://www.openstreetmap.org/user/mmd also known as https://github.com/mmd-osm

Maybe you can ping all three via the mentioned github issue?
