Actually, it's beening called as acceptable here (to determine if the 
newly created object can be moved from #-1 to the player).

I don't know what neat security features Frand's has on it for 
acceptable, but whatever they are John removed them in favor of the ones 
on #6 (which is the next ancestor defining acceptable).  The one on #6 
defines anything that's not a player as acceptable.  So, if I'm a 
programmer, and I control object x, I can move object x to you, unless 
object x is a player.
