I'm curious if the guy's actual use-case is even really a list, or if
that's being extrapolated out of the example he made of what he wanted to
be able to do. If these things are lists, they should live and die as
arrays, but then you can't export them.

If I could critique your solution a little,

Why do
IFS=' ' read -ra list <<< "${!v}"
instead of
list=( ${!v} )
?

And nameref variables could simplify what you're doing as well.
