Re: {ref}<&- does not work on array reference subscripts

[Grisha Levit]

Yikes, I missed the exec command in my example, that would certainly make it confusing..

What I meant was that the assignment works (i.e. the nameref is followed correctly), but the relevant code doesn’t handle retrieving the value of such a nameref when it needs to do so to close the descriptor:

$ declare -n ref=var[0]
$ exec {ref}</dev/null
$ declare -p var
declare -a var=([0]="10")
$ exec {ref}<&-
bash: ref: ambiguous redirect
