Is this bug or valid elisp (use of apostrophe in toplevel forms in edebug.el)?

[arthur miller]

I am still playing with elisp, and I have found some places in edebug.el which I don’t

Really understand. Several top-level forms are quoted.

For example:

;; Not used.

'(defun edebug-two-window-p () …

 

;; Not used.

'(defmacro edebug-save-restriction (&rest body) …

 

'(defvar edebug-display-buffer-list nil …

 

Etc

There are several of those places. If this just a fancy way to comment out code or does

it do something I don’t understand yet?

I am thankkfull for help, I am not so super-comfortable with elisp. I have checked manual

about commenting and quoting and I don’t seem this quoting fits into it, but maybe it is

used by byte compiler in some way I don’t understand yet?
