flush_cache

Empty a memoized function’s caches: flush_cache('name') or flush_cache(\&wrapper).

Both the scalar- and the list-context cache are cleared; the function stays memoized and starts refilling on the next call. Croaks ... not memoized for a function that is not currently memoized, and Tied cache hash for ... does not support flushing when a HASH cache is tied to a class without a CLEAR method. Not exported by default: use Memoize qw(flush_cache).
