Hash function might be a valid purpose, but I often find that there are 
specific members that you want to exclude from equality/hash for various 
reasons.  And hash function implementation should be tightly coupled to 
the structure definition anyway, so there's less reason to abstract it away.

I don't consider this library suitable for (de)serialization purposes 
since it provides no access to the member name.
