Yeay, that's exactly what I had in mind for my second try. I though I
would call this special object some kind of execution context.

I am very interested in both your code, and anything you can to tell us
about what worked well, and what you would do different.

Functionally language are clearly a very interesting alley to go down for
these problems. I am right now in Python, and staying there for a while,
but I believe I can learn a lot from functionnal languages.

Thanks for your feedback,
