def closest(tokens, search_vec, limit, offset=<NUM_LIT:0>):
return sorted(tokens,<EOL>key=lambda x: cosine(search_vec, word_vec(x)),<EOL>reverse=True)[offset:offset+limit]<EOL>
Return the <limit> words from <tokens> whose vectors most closely
    resemble the search_vec. Skip the first <offset> results.
