My personal opinion on it is to never use return values from ->forward.  If
you need the data, stick it in the stash.  I also find it very useful to
setup structured stash key definitions along with a glossary to keep things
sane.

For instance, if I'm holding onto any result sets in a chain, or forwards,
those always go to ->stash->{resultset}->{foo} (where foo is typically the
action name used to generate the resultset).

It's kept my applications extensible and pretty clean.
