;;; Note: We use strings rather than symbols because symbols are usually
;;; ``interned'', i.e., kept in a weakly-keyed hash table, thus making them
;;; inappropriate for the tests below. Furthermore, we use `string-copy' in
;;; order to make sure that no string is kept around in the interpreter
;;; unwillingly (e.g., in the source-property weak hash table).
