I apparently was sitting on a draft in this thread:

Hey Gina,

Is there potentially a 12th type of operation? It is implied multiple ti=
mes, but not spelled out: "offset exists" (i.e., "array_key_exists()" fo=
r arrays). The recent discussion on pattern matching makes it seem like =
there is potentially a huge difference between "an offset that exists" v=
s. "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 a=
ny case, why or why wouldn't it be considered an operation?
