In older versions of Catalyst, the application class was where you put
global actions. However, as of version 5.66, the recommended practice is
-to place such actions in a special Root controller (see #####, below),
-to avoid namespace collisions.

Catalyst automatically blesses a Context object into your application

Note that the stash should be used only for passing data in an
individual request cycle; it gets cleared at a new request. If you need

If C<default> isn't acting how you would expect, look at using a
-L</Literal> C<Path> action (with an empty path string). The difference is
-that C<Path> takes arguments relative from the namespace and C<default>
-I<always> takes arguments relative from the root, regardless of what

You normally render templates at the end of a request, so it's a perfect
use for the global C<end> action. (In practice, however, you would use a
