+  Sometimes it is useful to pattern match on multiple values at the same time in
+  one case experession.
+</p>
+<p>
+  To do this you can give multiple subjects and multiple patterns, separated
+  commas.
+</p>
+<p>
+  When matching on multiple subjects there must be the same number of patterns
+  as there are subjects. Try removing one of the <code>_,</code> sub-patterns to
+  see the compile time error that is returned.
