The intention is that they should work correctly for negative offsets.
It seemed more useful that way. Word.toIntX does imply that the basis
library understands signed word values.
Yes - the getX/setX operations are more useful by allowing negative
offsets. Unfortunately, the word offset can be viewed in an unsigned
way. I would suggest e.g.
getX : voidStar * int -> Word8.word
unless use of an int introduces more overhead.
I don't want to use "int" here for these very low-level functions. It
would require a tag test to check that it isn't a long-format arbitrary
precision number.
