 +======Synopsis:​======
 +$__diff__(<​word list 1> / <word list 2>)
 +
 +======Technical:​======
 +   * There must be a literal slash character ('/'​) that separates the two word lists. ​ If it is omitted the empty string is returned.
 +   * It is not required to have spaces on either side of the slash, but it also does not hurt to have them.
 +   * The return value is a word list comprised of the negated set-difference of <word list 1> and <word list 2>, that is to say:
 +   * The return value is a word list of all words that are in ONE BUT NOT BOTH of the word lists.
 +   * All extra whitespace around words will be lost.
 +   * Double quoted words are honored, but the double quotes will be lost in the return value.
 +
 +======Practical:​======
 +Use this function if you need to find the un-common elements of two 
 +different word lists. ​
 +
 +======Returns:​======
 +All words that are in either <word list 1> or <word list 2> but not both.
 +
 +======Examples:​======
 +<​file>​
 +$diff(one two three / two three four)     ​returns "one four"
 +$diff(one two / three four)               ​returns "one two three four"
 +</​file>​
