[Dbix-class] prefetch with +select

[Mark A. Stratman]

Is this a bug, or a necessary behavior? Or is there another way I should be doing a prefetch with +select?

$row = $rs->search({}, {
    '+select' => \'lower(something)',
    'prefetch' => "relationship",
})->first;

$row->relationship->first_column; # has the value of 'lower(something)'.

That is to say, every field in the "relationship" is shifted over by the +select.

Any insight would be appreciated.
Thanks,
