Incidentally, both you and Touretzky forgot that hash-tables have two
additional interesting properties beyond the :type and :size -- the
:rehash-size and :rehash-threshold. Hash-tables wouldn't be fully
reconstructable from the printed format unless this information were
also included.
That's not an unprecedented flaw. Arrays have a number of properties
that are not represented in their printed representations, such as
adjustability, fill pointer, and element type.
