My updated series already kills > off the be/uuid one, the le/guid one will need a bit more work, though. That works too. and for another argument, why need a helper uuid/guid_cmp when one can use C comparison (i.e. u1 != u2) ? assuming that we have no reason to abstract that fact that uuid_t/guid_t are a struct type.
