Thank you, that worked perfectly! I had to upgrade to new Coderunner version to see "Twig all" which worked very well. I know, the question was quite ambitious but although I didn't quite succeed at first, I learnt a few things about customization and internal structure. I agree with your "paedagogical equivalence" argument. I used your "1. using twig" suggestion successfully. Thanks :) I am very grateful, Coderunner is awesome.
