Whoa, cool.  And it even does cycles and sharing!  I wish I'd thought
to ask whether something like this existed, it'd have saved me a lot
of time writing serialization/unserialization code.

Now if only it did the right thing for hash tables:

> (print-convert (hash-table ('x 1) ('y 2)))
(make-hash-table)
