First, let's establish we are speaking of olives with pits. A poem is an exploration of the sweetmeat around a core. The olive pit is core.
By the way, a pit-less olive allows a poem to explore it's core in anyway is wishes. Be it void. Be it bowl.
So you see, there is losing with olives. Pit, pit-less, or however they be dressed.
No quite that easy with a poem, of course.
