Not sure if I am misreading something but according to the docs the order of preference is class_defaults < env < arguments, however, your test is proving that class_defaults < arguments < env. I might be misreading this completely but my tests seem to confirm this.

Ok, just realized that your test case is testing changing the order + using the __config_settings__ trick, not the default case. So all is good and I managed to get it working exactly as I wanted, thanks a lot!
