Agreed.

Indeed. I think what is meant is that with
(let ((x 17))
(lambda () (incf x)))
there is no symbol x but the lambda is actually a closure
(closure ((x . 17) t) nil (incf x))
where the value of x is stored in its closure environment. But here,
symbol-value will error anyway. I see no way to construct something
where there is both a symbol *and* a binding in the lexical environment.
