The `gv-expander` of `substring` uses the `cl--set-substring` function
that's defined only in `cl-lib`, so currently, you can compile
(setf (substring ...) ...)
without requiring `cl-lib` but at run time it will tend to signal
a `void-function` error.
We could autoload `cl--set-substring`, but I think a better choice is to
move this `gv-expander` to `cl-lib.el`.
There are 2 other place definitions in `gv.el` which similarly rely on
helper functions defined in `cl-lib` (namely `buffer-substring` and
`frame-visible-p`) which we could move as well, but since we marked
those as obsolete anyway I think we can "let them die" where they are,
with their quirks left alone. If you feel otherwise, I can update the
patch to move them to `cl-lib.el` as well.
