If @var{weak} is @code{value}, then the hash table does not prevent
values from being collected as garbage (if they are not referenced
anywhere else); if a particular value does get collected, the
corresponding association is removed from the hash table.
If @var{weak} is @code{key-or-value}, associations are removed from the
hash table when either their key or their value part would be collected
as garbage, not counting references to the key and value from weak hash
tables. Likewise, if @var{weak} is @code{key-and-value}, associations
are removed from the hash table when both their key and value would be
collected as garbage, again not considering references to the key and
value from weak hash tables.
The default for @var{weak} is @code{nil}, so that all keys and values
referenced in the hash table are preserved from garbage collection. If
@var{weak} is @code{t}, neither keys nor values are protected (that is,
