Is it 100% deterministic?

The verification is, which allows the optimisation to be extremely broad and non deterministic.

It's really unlike a compiler. For example, for a function like 'sort', the optimisation can:

- Use quicksort if the data distribution is generic.

- Use insertion sort if the data is nearly sorted

And so on... As long as these can be proven sound, Maxwell can pick the best optimisation in real time.
