The theory would be that is cleaner to call an object property than use a string
(when possible); compiler helps and so on...

   object->prop vs find_me_prop("prop")

Since all machine properties have already been set with the command line options
we really have no need to use them anymore and we can favor the machine.

Thanks,
Marcel
