the basic idea is that you have to put out the data in a format that
can be read back in; java and other languages call this "seriali-
zation" and it is a mostly-solved problem (although it's not trivial;
think especially of recursive or self-referencing data structures, and
what it means to "write those to disk" in a way that can be restored
into memory sanely).
