Yes and no. No, because if he knows who went he perforce knows
what an extension is -- if extensions are an integral part of
interrogatives. Yes, because my sentence says (in effect) that
John knows that he knows who went. It's debatable whether that's
a good thing or not; it seems the desired meaning for most but
not all situations we describe as "knowing who went".

He doesn't know da, though -- at least not by the way I defined
extension, which was (in essence) as the set of goers. I could
rethink it, more along the lines you've been working along,
such that the extension is the set of true answers, but I am
not yet convinced that my version above is wrong.

Oh aye, yes: that was obvious, wasn't it!

But given that ce'u in free ka is relatively clearly defined, and that
ka/ce'u are only defined as free, the bound ka usage being something
of a groping in the dark, bound ka should not have first claim on
ce'u, however much more frequently needed bound ka is than free ka.
So instead you should be looking for an alternative to ce'u -- an
experimental cmavo, if necessary.
