 synopsis:       Perfect minimal hashing implementation in native Haskell
 description:     A <https://en.wikipedia.org/wiki/Perfect_hash_function perfect hash function> for a set @S@ is a hash function that maps distinct elements in @S@ to a set of integers, with __no collisions__. A <https://en.wikipedia.org/wiki/Perfect_hash_function#Minimal_perfect_hash_function minimal perfect hash function> is a perfect hash function that maps @n@ keys to @n@ __consecutive__ integers, e.g. the numbers from @0@ to @n-1@.

                 The library is written generically to hash both strings and raw integers according to the <http://isthe.com/chongo/tech/comp/fnv/ FNV-1a algorithm>. Integers are split by octets before hashing.

-                = Caveats
-                Only integer keys of at most __32-bits__ have been demonstrated to work properly.  Since the hash function masks to 32 bits, colliding 64-bit integers can hang the lookup table construction.
