Q: how can I access a hash table by its value, not its key?
Association lists can be accessed via either their key or their value:
(setq alist '((a .1) (b . 2) (c . 3))) (assoc 'a alist) ; => (a . 1) (rassoc 3 alist) ; => (c . 3)
Is there a hash table analog to
rassoc that would allow me to find the key in the hash table associated with value?
