Yeah, `gv-ref` is not super popular, indeed. Can't blame you.

Oh, yeah, that as well.

Because in ELisp order of evaluation of function arguments is specified
to be "left to right" and code can (and does every once in a while) rely
on it. It's not super-frequent, but not really rare either (e.g. it's
quite common for things like `delete-region`).
