- Hash tables now support weak value, weak key-and-value, and
weak key-or-value tables. The :WEAK-P keyword argument can
take the following values with the given meanings:
T
For backward compatibility. It is the same as :KEY.
:KEY
The entry exists as long as the key is not
garbage-collected.
:VALUE
The entry exists as long as the value is not
garbage-collected.
:KEY-AND-VALUE
The entry exists as long as the key and the value are
alive.
:KEY-OR-VALUE
The entry exists as long as the key or the value are alive.
These tables are currently experimental, but appear to work.
