9 cananian 1.1.2.1 * <code>HCodeAndMaps</code> is a strongly-typed tuple representing
10 cananian 1.1.2.1 * all the derivation information for a cloned <code>HCode</code>.
11 cananian 1.1.2.1 * This includes the mappings from old <code>HCodeElement</code>s
12 cananian 1.1.2.1 * and <code>Temp</code>s to new <code>HCodeElement</code>s and
13 cananian 1.1.2.1 * <code>Temp</code>s as well as the identity of both the old
14 cananian 1.1.2.1 * <code>HCode</code> and newly cloned <code>HCode</code>.
15 cananian 1.1.2.1 * It is intended to make 'clone-then-mutate' operations more
16 cananian 1.1.2.1 * straight-forward to write.
