You want to put the data into the 'stash'.

So in your controller you have:
my ( $self, $c, $arg ) = @_;
$arg =~ s/stuff/munge/;
$c->stash->{somearg} = $arg;

And in your view, you say: [% c.stash.somearg %]

You don't really want the view to be able to see the controller's  
internal state / mechanics, and so you have to explicitly stash any  
data which you want to be able to see from the view.
