I'd say that this is a rather bad example. And it seems it's used as an example for TT because it's just that, an example.
In this (pretty rare) case I'd suggest having a login validation action, and grant/deny access with a specified message (Too young, much too young). This message can then be displayed in the login template itself. So view logic is a clean and easy
[% login_message %], and the back set's the reason into
$c->stash->{ login_message }.
