So GHC's Int/Word implementation is different from Hugs'? Hugs
represents Word8 (say) by a 32 bit int but doesn't guarantee that the
top 24 bits are all zero. Instead we either use an 8-bit operation
when we operate on a word8 or we mask the arguments and use the 32-bit
operation (for *, /, ==, etc.) or we don't mask and use the 32-bit
operation (works for and, or, +, and some of the shifts)
