Me:

I was thinking about this and I would like to ask the question the other way: regardless the fact that English Future Simple cannot be translated into Klingon perfective, would *wa'leS rep wa'maH loS jISoppu', ghIq juH vIjaHpu'* make any sense in Klingon without giving it an interpretation of perfect (*Tomorrow at 2 p.m. I will have eaten*)? I mean, is it possible to interpret it as a future counterpart of the past perfective *wa'Hu' rep wa'maH loS jISoppu', ghIq juH vIjaHpu'* (*Yesterday, I ate at 2 p.m. and then I went home*)?

I mean: considering the action as a completed whole in the future, without showing how it unfolds or its internal structure and without referring its result to the (later) time context.
