 +======Synopsis:======
 +$__qword__(<index> <list>)
 +
 +======Technical:======
 +   * If the <index> argument is omitted, the empty string is returned.
 +   * If the <list> argument is omitted, the empty string is returned.
 +   * The <index> argument is taken as an integer number.
 +   * If <index> is a negative number, the empty string is returned.
 +   * The return value is the <index>th word in <list>, counting from zero.
 +   * Remember that <list> is always a list of [[what is a word|words]].
 +   * In either case, if the return value is double-quoted if it contains a space.
 +   * If <index> is greater than the number of words in <list>, the empty string is returned.
 +
 +======Practical:======
 +Use this function when you need to extract a specific word from a list.
