Meaning multiple directories and people share with those with systems with similar characteristics? It certainly is better than silently getting confused or barfing when reading 32LE data on 64BE box, and presumably it would be easy to implement, but is that the best we can do with memoize?

I am wondering if memoize can be told to use a platform independent serializer backend that is reasonably efficient.
