Dunno about ORMs in general, but being able to pass a DBIx::Class
object into a TT template and have the template query the various
values and pull out the things they want seems like a big win.
Especially the object chaining
my $vars = { module => $db->resultset('Module')->single({ ...some
criteria ...}) };
$template->process('mytemplate.tt', $vars)
[% module.author.email | html %]
I'm not sure it's the best example - I'm thinking about where your
tables are connected in the schema, which lets you query tables that
can join the 'module' table simply by using . in the template. Thus
the above 'module' table would only contain an 'author_id' column, and
the 'author' table would contain the 'email' column.

I have in the past been wary of ORMs where you spend all your time
learning the implementation details and being comfortably numb about
the underlying theory.
DBIx::Class I've taken a strong liking to tho fwiw. Like jquery, when
the abstraction is done well, it makes a lot of things better/shorter.
