Are you talking about doing this?

$c->stash->{list} = [ Model->retrieve_all ];

in template:
[% FOR item IN list %]
   <tr><td>[% item.field1 %]</td><td>[% item.field2 %]</td>....
[% END %]

As far as I know this is the standard way of using CDBI objects in TT. 
It's technically "retrieved" in the view, but it's sure better than the 
HTML::Template-style way of doing it where you had to create your own 
giant arrayref/hashref structure to pass to the template.
