Sorry, this works:

void main() {
  auto tt = Tree(5, [Tree(7,[Tree(11), Tree(4)]), Tree(10)]);
  foreach(v; TreeRange(tt)){
    writef("%2d, ", v);
  }
  writeln();
  for(auto r = TreeRange(tt); !r.empty; r.popFront())
    writef("%2d, ", r.front);
  writeln();
}

I needed this:

struct TreeRange{
  this (this){ throw new Exception("TreeRange is noncopyable!"); }
  ...
}

Or use class :)
