So then you get what? The exact same thing, with all the attendant flaws, as declare -p which is already known not to work? You still have to sed/grep the contents, and you still have the original declare -p problem that you need to parse the value of the variable in order to figure out *where* it is so you can discard and ignore it... which is impractical without an actual shell parser. -- Eli Schwartz
