So, in my opinion, your original suggestion is still the best one, even though I did not seem to agree at first. ;-)

OK.

If not, then maybe we should have a hash_combine that just combines hashes. At the moment the combining is mixed in with the getting; it's not a very orthogonal API.

Cool. (And this is another argument for adding the non-zero fix in hash_combine rather than hash_value.) -- Dave Harris, Nottingham, UK
