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 5.5 cl:make-hash-table in implementation.htm.
The documentation is described in introduction.htm and the index is in index.htm.
