I don't think I follow what you're saying, but let me try to be clear
what I expect, which is that (eval `(lambda () (foo ,v))) take the same
amount of time no matter what v is, if (foo x) expands into (quote x).
I don't want the expander to have to touch v at all.  This is currently
the case with Chez Scheme and with the portable syntax-case expander.
If the expander scans through v looking for potential implicit exports
because it can't be sure that (foo x) expands to (quote x), this won't
be the case.
