It's even more important to provide this functionality in boost as the LWG obviously decided not yet to include these (IMO crucial) extensions into TR1:
I agree, but should it be available in Boost.Tr1? I guess that I could provide two different versions: boost::hash, which implements Peter's version, and std::tr1::hash, which is a strict implementation of the standard, but uses boost::hash_value as an implementation detail (so there isn't much code duplication). Although if I do that, I should probably also provide two different versions of the unordered associative container - with different default hash functions. But that's pretty easy to do, just a bit messy. Daniel
