Well, "inverse" keyword sets the internal INVERTED_FLAG and just like all bit
flags it is promoted and then handled by the object intersection code itself.
Consequently an object is either inverted or it is nor.  Thus the inverse flag
is always "optimised" also the correct term would probably be "promoted".
