Detect that the current Emacs is Emacs Plus

[vmsp]

I'd like a way of detecting in my init.el that the current version of Emacs is Emacs Plus.

My use case is figuring out if exec-path-from-shell should be installed and executed, since Emacs Plus already sets the PATH to the correct value. Something like:

(use-package exec-path-from-shell
  :if (and (memq window-system '(mac ns))
           is-emacs-plus)
  :config
  (exec-path-from-shell-initialize))

I can sort of do this already in Mituharu's port because window-system will be set to 'mac.

i do this by doing the following: (boundp 'ns-system-appearance)

while its not specific to emacs-plus (that symbol comes in from the patch that provides the ns-system-appearance-change-functions hook), it might work well enough for your purposes!
