Note that the expression

     (list 1 2 (function (lambda () (with-current-buffer))))

can be rejected by the compiler (not enough arguments to the
with-current-buffer macro) whereas

     '(1 2 (function (lambda () (with-current-buffer))))

can't because it's just a quoted constant which just happens to look like
invalid code.
