What do you think of 'Programming with a Differentiable Forth Interpreter'[0] and 'A Neural Forth Abstract Machine'[1]? I don't know if they are related to your work, but both are on my to-read pile.
I think these papers are fascinating! I would also recommend the Neural Turing Machine paper from DeepMind, which I know better than the papers you mention.
But keep in mind that this is a very young field, and there is no definitive point of view.
