puthash-key

Arguments: key hash-table

As a side effect, may add an entry to a sans values (a key-only) hash table (one created with the values argument to make-hash-table specified nil), if the equivalent key entry is not already in the table. Regardless of whether the given key was added or an equivalent entry is found, puthash-key returns the key that is actually in the hash-table. This allows objects to be kept in a hash-table efficiently without duplication.

See the description of extensions to make-hash-table in cl:make-hash-table in implementation.htm.
