Nice - I was not aware of that. The following definition seems to work
(see also the patch at the end of this mail)
> --8<---------------cut here---------------start------------->8---
(define-public emacs-exwm-next
  (package
    (inherit emacs-exwm)
    (name "emacs-exwm-next")
    (synopsis "Emacs X window manager using the next version of emacs")
    (inputs
     (cons
      `("emacs-next" ,emacs-next)
      (delete `("emacs" ,emacs)
              (package-inputs emacs-exwm))))))

I have to admit that I do not understand that part. If I change it to
emacs-next, the build fails with the error
> --8<---------------cut here---------------start------------->8---
phase `install' succeeded after 0.0 seconds
starting phase `make-autoloads'
Wrong type argument: stringp, nil

It is a bit difficult for me to understand what is going on here,
because, like I said, I do not really understand this part of the
package definition in the first place - sorry. However, without
modifying the arguments, everything seems to work.

The following patch seems to work (do I need to send it on its own? I am
new to this type of workflow.)

Best
Dario
