Unmemoize
Turn off memoization for the specified function
Example:
(unmemoize 'foo) ; turn off memoization of foo
General Form:
(unmemoize fn)
where fn evaluates to a function symbol that is currently memoized;
see memoize. An exception is that as with memoize, fn may
evaluate to the name of a macro that is associated with such a function
symbol; see macro-aliases-table.
Calls of this macro generate events of the form (table memoize-table fn
nil). When successful, the returned value is of the form (mv nil
function-symbol state).
To remove the effects of all memoize events, evaluate:
(clear-memo-table). To save and restore memoization, see save-and-clear-memoization-settings and see restore-memoization-settings. These are both legal event forms.
Note: These events do not affect memoization from memoize events that
either are derived from calls of memoize-partial or have a
non-nil value of memoize argument :invoke
