I understand (I think ...) what :once-asked *does*, I want to know what it *means*.
In other words, the other two options seem to answer the question "when is this cell lazy?" Well, an :always cell is always lazy -- it's not recalculated until and unless you ask for it. An :until-asked cell is lazy until you query it once, then it's non-lazy from then on.
"once-asked" seems to answer a *different* question, "when is this cell evaluated?" It's evaluated once, when created, and then only when queried.
Is there any single "question" that all three answer, or are they just inconsistent?
Once-asked would be "un-lazy until you query it once" (ie, consistent) but it also looks to be vestigial: all code seems to treat it the same as always.
If I missed it in my brief scan of the code, it would have to do with model instance initialization.
Yeah, looks like I missed it, because the code looks for other than :once-asked to break off initialization and I was just searching on once-asked.
