hey Alex.. thanks for review. I'd done most of these already but I can't seem to push commits right now (whole afternoon it's been impossible). Hopefully I'll get the your suggestions up just now..
`return_models` sounds good to me. I'll make that so.
This warning is also gonna be replaced with a if(..) type warning as this way it's annoying and appears regardless of your choice of 'old_return'.. Thanks again :)
