This is more clear, and in fact, ok for me (if subscripted means

The same language appears in the "Shell Parameters" section of the manual
at the above link, just as it does in the "PARAMETERS" section of the
manual page.
in fact, I didn't see this. The #Bash-Builtins section misled me. Sorry!
By the way, I have seen that the nameref works more or less for functions:
$ foo() { echo "hello" ;}
$ declare -n bar=foo
but the reference has to be dereferenced when calling:
$ ${!bar}

is it still the case in bash 5?
Sure, it seems harmless to allow it.
I mean, I was surprised I couldn't simply run
$ bar

thanks for your fast responses
Cheers, Edouard

PS I love teaching bash :)
