Hello,

Thanks for the update. I merged the consecutive phases with
emacs-substitute-variables for clarity, and enabled tests with "#:tests?
#true". I'm sending the package definition in its current state:

Unfortunately, one test is failing with the following output:

Do you think this can be fixed? Or shall we skip that test?
