doc: `:local-nicknames` lost switching to `(defpackage)` [Package FILESYSTEM does not exist.]

[WillForan]

I started coding in emacs/sly using (in-package :ciel-user) but got far enough in that switching to defpackage made sense (5am testing!).

The initial code used things like (filesystem:directory-exists-p ...) -- packages with ciel local-nicknames. But sly-buffer-eval after switching to (defpackage ... (:use :cl :ciel)) threw errors

Package FILESYSTEM does not exist.

I peaked into packages.lisp and just copied the nicknames I needed.

(defpackage mrqart
  (:use :cl :ciel)
  (:local-nicknames
   (:filesystem :uiop/filesystem)
   (:notify :org.shirakumo.file-notify))
  (:export get-dcm-values *dcmtags*))

Is this the right move? Worth documenting? Maybe in one of

• 5am notes
• cel as library

(Thanks for this amazingly useful curated lisp experience!)

Hello, it looks like you did right and it's a documentation issue. A soon as we create our own package, we need to copy over the package-local nicknames.
