I apparently was sitting on a draft in this thread: Hey Gina, Is there potentially a 12th type of operation? It is implied multiple times, but not spelled out: "offset exists" (i.e., "array_key_exists()" for arrays). The recent discussion on pattern matching makes it seem like there is potentially a huge difference between "an offset that exists" vs. "an offset with no value"; whether or not that is the case, I believe it is an operation on a container? Maybe. I believe you are the subject-matter-expert on this, by this point, for sure; so you would know. In any case, why or why wouldn't it be considered an operation? — Rob
