You know, this implementation advice sounds pretty silly:

Implementation Advice
7/2
     The various Hash functions should be good hash functions, returning a wide spread of values for different string values. It should be unlikely for similar strings to return the same value.

As if any implementor needs to be told that they should use a "good" rather than a "bad"
hash function!
