   102 <li>Tuples are a new data type: sequences with <i>spin</i>. A tuple can be either spin-up or spin-down.

   103 </li>

   104 <li>A pair of compatible tuples can be <b>contracted</b> into a single number.

   105 <ul>

   106 <li>Tuples are compatible if they have the same length and opposite

   107     spin, and if their corresponding pairs of items are either both

   108     numbers or both compatible tuples.

   109 </li>

   110 <li>To contract tuples, take the sum of the products of corresponding

   111     pairs of items. (To take the product of compatible tuples,

   112     contract them.)
