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.
