What is the consensus on returning values from a call to forward?
I've seen a mailing list post stating that one should not rely on return
values from forward():
http://www.mail-archive.com/[email protected]/msg03519.html
But the Catalyst docs seem to indicate that returning values is allowed
as long as you are aware of the the consequences:

Anyways, just wanted to get a sense of what people think.

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.
