| although making $(()) handle 64-bit may also be a nice addition.
64-bit archs already support 64-bit $(()). 32-bit archs do not.
Well, at least the common examples for these platforms:
[weerd@impreza] $ machine
amd64
[weerd@impreza] $ echo $((1024*1024*1024*5))
5368709120
[weerd@tuna] $ machine
i386
[weerd@tuna] $ echo $((1024*1024*1024*5))
