For infinite precision integer in particular you need access to the carry bit that is generated by vector artihmetic and other instruction level features. Just replacing int with int_128_t isn't going to get you too far.
Of course, again you put word in my mouth. The underlying representation can still be some int arrays, you just need to work on them using a range adaptor outputing SIMD register filled with data on the fly. It is a specialization of the memory allocator and of the algorithm.
I said some will disagree to acknowledge that this was my opinion and not an absolute truth. I was trying to speak for myself. Regards, Luke
