To read an array by name:
f() {
local array_name=$1
print -rl -- "${(@P)array_name}"
}
typeset -a foo=(bar baz)
f foo
To write an array by name:
f() { set -A "$1" bar baz }
typeset -a foo
f foo
> Or how can I return the new array and set the old one's value to that?
f() { reply=( bar baz ) }
typeset -a foo
f
foo=( "${reply[@]}" )

gmane.comp.shells.zsh.user and zsh-users@zsh.org are the same thing. ☺
