+<p>
+  The <code>panic</code> keyword is similar to <code>todo</code> keyword, but it
+  is used to crash the program when the program has reached a point that should
+  never be reached.
+</p>
+<p>
+  This keyword should almost never be used! It may be useful in initial
+  prototypes and scripts, but its use in a library or production application is
+  a sign that the design could be improved. With well designed types the type
+  system can typically be used to make these invalid states unrepresentable.
