Yes, that's true, and makes sense when I think about it. But the
manual page doesn't consistently phrase it that way:

It shouldn't be. Bash executes PROMPT_COMMAND before it calls readline to
read the first line of a command.
it may also be config path error cause i didnt PREFIX or so cause i dont

hm how can i help
its a fresh deb all-tree's system, i had bash 5.1.4-maint from a month or
so ago ( only binary from another system ) and fetched the new today and
compiled and installed, and cp'd to /bin
i suspect it could be internal readline short bindings issue, instdead of

You need at least ncurses-devel (or ncurses) so bash configure can find
the terminfo library it needs to look up terminal control character
sequences, and bash can

Would this be the right place to discuss Readline as well as propose
features?
To not waste anyone's time, I'd also include an actual readline question
I have:
If readline is included in an ncurses software that also uses its own
keybindings for things, how would that work?

When using edit-and-execute-command to edit the command-line I've
noticed that PROMPT_COMMAND is not evaluated upon returning to the
prompt, e.g.:
earnest i ~ PROMPT_COMMAND='echo foobar'
foobar
earnest i ~ set -x

foobar

as for goal, and no believance, it is handling quoting, string issues,
nothing else
you may know if you think about it im a freelance code there is nothing now
but major functionality issues

what, dude, of course you can regex eerything right
that is, for no quotes

for " its till nonescaped "
and for $' till nonescaped '
i can regex it or extglob it
hm ?
but i need the results of grouping of the matches ( '( .. )' )

That's a feature request. Chet can discuss that with you.
All I can tell you is that this feature is not in
wheres the sense of not having same var format rules as.. normal, but not
for unset ?
i can do arr[$key]= without problems, cool, why bug around big in unset
( aka choose keywords instead of lower for, ... important functionality )

You don't write bash code
as i got suggested here for help-bash for new ..
there is ways to crop data to wanted by cropping the excludes out
but where is the simple way of keeping matching
i'd say implent backtrack references for @( .. ) etc groups
pseudo exmaple
declare -A big=( mess of data )
var=$( declare -p big )

Bash has 5 types of quoting: '...', "...", $'...', $"..." and backslash.
$'...' is a form of quoting,
