Nor is it mine. I'm sorry to react like this, but this kind of
(seamingly not well argumented) affirmation can hurt people that
worked for years on this kind of topics.

Is Dolphin's interpreter available on a wide variety of architectures?

I would be glad to see your code then. Especially the nat implementation.

Yes, native support for bignums is a win (as I mentioned earlier, it is
very convenient to input numbers)
