you save just about any data structure to disk (except threads,
streams and objects which don't have a print-object method) by simply
compiling a file containig:
(setf *data-structure-root* '#.*data-structure-root*)
that file, when loaded, will set *data-structure-root* to whatever
value it had when the file was compiled. this technique, while
occasionally usefull, does have some limits:
1) apparently (but i didn't spend too much time looking into it) you
can not save more than 2^32-1 distinct objects in a single file.
2) compiling is slow (loading is quite fast though).
your other option is to just use save-application.
Ring the bells that still can ring.
Forget the perfect offering.
There is a crack in everything.
That's how the light gets in.
