In the definition of a weak map that I have always known, the key does not keep the mapped value alive. In the weakmaps proposal the key keeps the mapped value alive. So if you can ever lookup a key again, the value cannot be collected, so your "cache" will hold onto every entry forever. > David --Oliver _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
