Concerning the hashing of integers,
There is a great new book by Andres Valloud,
called "Hashing in Smalltalk: Theory and Practice."
Anyone concerned with hashing should read this book.
Its relevance here is that there are excellent reasons
for letting the hash of fixnums be themselves.
Someone, was it Jan, said:
>> I think the new implementation is better as it guarantees proper
>> distribution when hashing integers that have some pattern.
It can't. No hashing method can possibly do that.
