Hi The R6RS states:
*"Hash-function* should accept a key as an argument and should return a non-negative exact integer object." This only the only place that mentions a non-negative integer. What is the rationale for making the hash value non-negative? By constraining the output, you are limiting the usage of fixnums and might have to resort to big nums.
