> Can we modify literal objects? 

No, and the manual should do a much better job at explaining this. At the very least it should not promulgate bad ideas by including mutation of literals in example code. Patch attached, suggested for emacs-27.

We should not even try to show what happens when the user breaks the rule, because it is undefined.
