Something that I still don't think has been made very clear in this discussion that I'm very curious about: How efficient would these large fixed-size ints be (on 32-bit hardware)? Would they be almost as fast as 64-bit, almost as slow as bigints, or somewhere roughly in the middle? Obviously on 64-bit hardware they can be made fast, but if that's the only place they can be made fast, then I think it's more important that DMD support 64-bit hardware first.
