+  program. It is similar to the <code>panic</code> keyword in that it crashes
+  when the program has reached a point that should never be reached.

+  <code>let assert</code> is similar to <code>let</code> in that it is a way to
+  assign values to variables, but it is different in that the pattern can be
+  <i>partial</i>. The pattern does not need to match every possible value of the
+  type being assigned.
