Thanks for the update. I'm sorry: I pointed you, as an example, to
a package using old syntax.

We're now using G-expressions, which are less ambiguous than quasi-quotes:

(arguments
 (list
  #:phases
  #~(modify-phases %standard-phases

We don't use (assoc-ref inputs ...) expressions anymore. It is possible
to replace those calls with `search-input-file'.

For example, here, it is possible to write

  (string-append "\"" (search-input-file inputs "/bin/xclip") "\"")

> +                        #t)))))

Phases do not need to end with "#t" anymore, so this can be dropped.

I made the changes above on your behalf and applied your patch.
