Is it possible to get all OSM nodes (are not belong to any way) using the Overpass API?

I want to get all OSM nodes (are not belong to any way).
Is it possible?

Understandably, this query get all nodes (includes member of ways)...

<osm-script output="json">
    <query type="node">
      <bbox-query {{bbox}}/>
    </query>
    <print/>
</osm-script>

I tried tyr's query and success!

Solution

Actually, this is possible since the latest version of Overpass API:

<osm-script output="json">
  <query type="way">
    <bbox-query {{bbox}}/>
  </query>
  <recurse type="way-node" into="waynodes"/>
  <query type="node" into="allnodes">
    <bbox-query {{bbox}}/>
  </query>
  <difference>
    <item set="allnodes"/>
    <item set="waynodes"/>
  </difference>
  <print/>
</osm-script>

This uses the difference operator to subtract nodes that are member of any ways from all of the nodes.
