I'm afraid it's not a reference. Looking back, I don't see how it
Oh well. He has a very interesting technique of using multidimensional
array types to represent sequences of integers:
I think many compilers might like this better than list<int_c<i0>,
int_c<i1>, ...>. We'd just need to define the appropriate iterators.
