Thanks, installed.

To the extent that the code doesn't take advantage of lexical scoping,
it doesn't matter because it will still work just as well as before on
Emacs<24.

The first Emacs that came with `package.el` was Emacs-24, which is also
the first that came with `lexical-binding`.
There have been versions of `package.el` patched to work in Emacs<24
(not sure how far back it worked), but indeed I tend to consider
Emacs-24 as the "baseline" for ELPA packages.
