I meant after ^, ~, @{} have been peeled off. Just before resolving what's left.

I wanted to explain it through an implementation, but okay. In your proposal, @ is a special ref: it behaves like a ref in a rev spec, but cannot be update-ref'ed or symbolic-ref'ed. This is probably the best we can do, unless we want to emulate a full ref (I'm not sure how useful the .git/@ override will even be).
