Sorry for missing it earlier. I think something like attached should fix the problem, if we want to continue with the current example. FWIW, it demos that quotes can be used with labels, but we don't necessarily do that with other objects. I am not sure whether Peter would like to continue with the example or use a different one avoiding this subtlety altogether. Hence not including it in the overall patchset. -- Best Wishes, Ashutosh Bapat
