[Dbix-class] What should DBIC objects stringify to?

While programming in CDBI I got used to this paradigm:
$obj = $something->search({whatever});
if ($obj) {
    # do something with the result
} else {
    # we got an empty result

In other words, in CDBI results stringify (if that's the wrong word, 
please enlighten me) into undef (or some other false value) if they 
don't contain any elements, and to the primary key otherwise.

I understand that this is somewhat trickier with DBIC, considering DBIC 
objects can easily have multiple primary keys.

But could we still have something resolving to a false value when a 
search returns
nothing? Or am I missing something in the docs?
