Speaking as an ex-mathematician, prove is a very strong word.
I purposely used such a loaded word. But, in some sense, that's
the issue. If you depend on an "obscure" property and you can't even
*begin* to try to prove it's true, it's a very dubious thing to
be depending on.
For speed, the small ones probably still should be linearly
addressable. But, we should profile.
Hashing functions can be quite fast. I doubt it would be worth the
complexity. I certainly agree about profiling, though.
