In Perl, certain things will only work with 32 bits. But math can handle integers up to about 56 bits.

Checking the source for Set::IntSpan, I find the evil: use integer; so you can probably just comment out that line and suddenly be able to use 56-bit values. A note to the author to "fix" this would also be appreciated.
