i meant to say these should work:

the only way i was able to get code working was doing that. its not
pretty, and i'll update it as soon as rose supports it-- but I needed
to get some functionality into a project.

I only meant for null objects when with_loaded fetches nothing, but
tried to fetch something -- not for marking the namespace on all gets.
that shouldn't imply that anything that exists in the db isn't in the
result set, any more than other parameters you stick into a manager
subroutine
ie ( please excuse pseudocode and me using hashes to convey this idea )
# current behavior
my $results= get_items( with_objects=['a'] );
$results= {
'id'=> 1
'name=> 'jon'
}
# wanted behavior
my $results2= get_items( with_objects=['a'] );
$results2= {
'id'=> 1
'name=> 'jon'
a=>[ ] # one to many
}
$results2= {
'id'=> 1
'name=> 'jon'
a=>{} # one to one
}
