The man page berates old-timers:
When the old-style backquote form of substitution is used...
However, who is it that is too hungry for the next ")"?:
$ k=$(case x in x) :;; esac)
bash: syntax error near unexpected token `;;'
$ k=$(case x in x) :; esac)
bash: syntax error near unexpected token `esac'
$ k=`case x in x) :; esac`
$
The man page even mentions:
Command substitutions may be nested. To nest when using the
backquoted form, escape the inner backquotes with backslashes.
But tripping/conflict over case esac innards hadn't been discovered
until today for $() so isn't mentioned. Fix the "bug" or mention it
here and in the "case ... esac" sections of all docs.
By the way,

(It is more likely that the source will modify me. Anyway, I end up
pasting with the mouse 30 times a day. I have only once in my life
used ^R.....ESC. or ^P^P^P...ESC. as offered.)
