Ok, I'll buy the first one off you (although you can work round it), but I'm not sure about the second one.

Most CPUs generally don't have don't have 128-bit and 256-bit arithmetic operators and passing big integers isn't fully supported by Windows and UNIX function calling conventions, so everything's got to be done by software anyway. That and the article was about saving space on FGPAs, not having big integers. But yes, I guess they would be nice to have.
