You could also consider changing your url layout to be more like:

URLs:
/myapp/users/list
/myapp/users/add
/myapp/users/add_confirm
/myapp/users/view[/username]

myapp::users.pm:

sub default ( redirects to users/list )
sub list/add/add_confirm ( do the obvious )
sub view : Local {
   my ($self, $c) = @_;

   my $username = $c->req->args->[0];

   $c->res->redirect('list') if !$username;

   ......
}

Now the usernames and the other actions are not stepping in the same
URI path-space, the username is a simple $c->req->args thing, and no
regexes or magic selectors involved.  Basically, the extra path
information on the end of view is PATH_INFO, which becomes the
$c->req->args arrayref.
