What do you mean by unordered? If the zeroth index is hashed, container
equality will fail to compile. In all other cases, equality depends on the ordering
of the elements, which is not strictly determined for ordered_non_unique,
sequenced and random_access. This might not coincide with your required
notion for equality. I simply mimicked the modus operandi of STL containers.

Yes, that's what I meant to say :)

Thanks and best regards,
