Unfortunately, it looks like I said the exact opposite of what I meant
to say.  My actual words are nonsensical, because they imply that we
should resolve "auto" away at computed-value time even when it can't
be done until used-value time.

What I *meant* to say is "It should just resolve at used-value time".
That is, a given keyword should always resolve at a single time; if
it's possible to resolve it at several different times, resolve it at
the earliest time that satisfies all cases.
