It does look like auto-chaining, so perhaps I should restate my original
question.

What I want to do is a bit more specific.
I am using chaining a decent amount, often chaining across different
controllers.

The end result of what I want to do is pass into the template (TT) the
top most level controller name IE the controller closest to root.
This is accessed using $c->namespace, from within the controller.

If I use auto-chaining like:

    sub auto : Private {
        my ( $self, $c ) =3D @_;
        $c->stash->{ controller } =3D $c->namespace;
    }

in the root controller (Root.pm). It works until I chain across more
than one controller.
Instead of the first, it gives me last controller in the chain, which
leads me to believe that this method is either called once for each
controller or called only once, but from the last controller in the chain.

Perhaps there is a different approach with autochaining I should try.
