Andrei Alexandrescu:
My suggestion is to focus on fixed arbitrary-sized integers in Phobos, and then add optimizations for 64-bit integers on architectures that support it.
I think library-defined fixed arbitrary-sized integers and built-in cent/ucent types are both useful to have. One doesn't fully replace the other. cent/ucent is more efficient (even on 32 bit systems), while FixedInt is more flexible.
But both are low-priority. Bye, bearophile
