Sorry to jump in, but I recently asked about a way to cleanly dump and
restore a hashtable.  Can that work coincide with the enhancement Eric
is discussing, which if I understand correctly is a condensed prin1
suitable for debugging?  I mention it because it seems sensible to think
both in the direction of Eric's work and in the direction of deeper
inspection of the built-in Emacs Lisp data structures.  Maybe it can be
simply a "dump level" parameter to prin1, going from "condensed" to
"normal" to "deep," separate from the print-level parameter or joined
with it.

I don't know print.c (yet), but if no one else is interested in doing
this, I can put the hashtable dump functionality on my TODO list.

Thanks
