 ** `dolist' in lexical-binding mode does not bind VAR in RESULT any more.
 VAR was bound to nil which was not tremendously useful and just lead to
 spurious warnings about an unused var.

-;; ============
-;; Freezing transforms a `defadvice' into a redefining `defun/defmacro'
-;; for the advised function without keeping any advice information. This
-;; feature was jwz's idea: It generates a dumpable function definition
-;; whose documentation can be written to the DOC file, and the generated
-;; code does not need any Advice runtime support. Of course, frozen advices
-;; cannot be undone.
-
-;; Freezing only considers the advice of the particular `defadvice', other
-;; already existing advices for the same function will be ignored. To ensure
-;; proper interaction when an already advised function gets redefined with
-;; a frozen advice, frozen advices always use the actual original definition
-;; of the function, i.e., they are always at the core of the onion. E.g., if
-;; an already advised function gets redefined with a frozen advice and then
-;; unadvised, the frozen advice remains as the new definition of the function.
-
-;; While multiple freeze advices for a single function or freeze-advising
-;; of an already advised function are possible, they are better avoided,
-;; because definition/compile/load ordering is relevant, and it becomes
-;; incomprehensible pretty quickly.
