It's not that I, personally, wouldn't have to take type/size/endianness
into account if I built something on top of a buffer in which
type/size/endianness matters.  It's that I wouldn't have to get a concensus
from anyone else on how to do so.

I'd define my __getstate__/__setstate__ for a class to work with a tuple of
(type, endian, size, buffer, ...) if needed, and someone else could define
theirs however fit their needs.  The buffer itself would just pickle from
mutable-bytes to mutable-bytes (hopefully with the same alignment that
malloc provides for the native machine).

Cheers,
