Well, you can always splice the list yourself, which has the advantage of
being more explicit and clear to a reader:
my $bars = $foo->bars; # reference to actual list
my $i = 0;
while(my $obj = $bars->[$i])
{
if(...)
{
$obj->delete;
splice(@$bars, $i, 1);
next;
}
$i++;
}
OTOH, I can see how some people might expect this to automagically delete
the object from the list:
foreach my $obj ($foo->bars)
{
$obj->delete if(...);
}
I'll think about it.

I think that's a bad idea. If you're doing a lot of queries with_objects
where those objects may or may not be there, I want them to really not be
there when they're not there :) To make the tests easier, perhaps a
has_related() Helper method?
if($obj->has_related('bars')) { ... }
