+Summary: Reachability of constant switches
+
+class T {
+	static int Main ()
+	{
+		switch (1) {
+			case 1:
+				return 0;
+			default:
+				break;
+		}
+	}
+}
+
+Should compile. Since the switch value is constant, we only have to look at
+the `1' case. Even though the default case does not return it does not
+matter, as it cant be reached.
+
+`The statement list of a given switch section is reachable if the switch
+statement is reachable and at least one of the following is true: ... The
+switch expression is a constant value that matches a case label in the
+switch section.'
+
+From 15.7.2 The switch statement.
