Re: mapfile creates poorly-named array if passed nameref to array subscript

[Grisha Levit]

I guess it’s even more general than just list assignments. See also below problems with declare:

$ declare -n ref=var[123]; unset ref; declare ref=; declare -p ${!ref}
declare -- var[123]="123]"

$ declare -n ref=var[123]; unset ref; declare ref+=; declare -p ${!ref}
declare -- var[123]="23]"

$ declare -n ref=var[123]; unset ref; declare +t ref; ref=X; declare -p ${!ref}
declare -- var[123]="X"

(The +t above can be replaced with any other flag)
