Now, we can start considering what it'd mean for an accusative complement of a verb not to be an object. This would mean we can't coordinate them, despite identical marking, with other objects:
*John wasat and hated schoolThis in itself is kind of interesting. However, we could imagine something really weird going on here: using some kind of circumstantial (or whatever) voice to turn these verbs into actual transitive verbs; then, some voice marker could be used to permit something along the lines of
John was being be-at-ening and hated schoolwhere obviously be-at-ening is a pretend form in English, a nonsense thing I use to present this form. This use of voice would probably have to be called something like explicit active or somesuch.
