Unfortunately none of the basic kernels (Simple_*) make any guarantees
about how their objects are laid out. You can probably take a look at
the individual classes and decide if you can serialize what is there
with Cartesian_const_iterator or by accessing the right
coordinates. This will be rather fragile, do it at your own peril.

The whole idea seems difficult for reference counted and impossible for
Lazy kernels.
