@Override
  public void meet(Var var) {
    if (!var.isAnonymous()) {
      varNames.add(var.getName());

@Override
public void meet(Var node)
  throws RuntimeException
{
  // take only real vars, i.e. ignore blank nodes
  if (!node.hasValue() && !node.isAnonymous())
    res.add(node.getName());
}
// TODO maybe stop tree traversal in nested SERVICE?
