A more corner case is:
(defvar-local my-foo :default)
(with-temp-buffer
(let ((my-foo :global-let))
(with-temp-buffer
(setq my-foo :set)
(list my-foo (with-temp-buffer my-foo)))))
vs
(defvar-local my-foo :default)
(with-temp-buffer
(let ((my-foo :global-let))
(setq my-foo :set)
(list my-foo (with-temp-buffer my-foo))))
IIRC this is done purposefully (the code has to work harder to get this
semantics), but not really documented, and I can't offhand give you
a good reason for that semantics.
