Thanks. I changed things of the form

r=($(eval "echo "\${${a_all[1]}[@]}\""))
to
eval "r=(\"\${${a_all[1]}[@]}\")"

One place where I can't see how to eliminate the construct is where I pass in 
the name of an array and parse it using set

set -- $(eval echo \"\${$name[@]}\")

would I be better off with something like

eval "set -- \"\${$name[@]}\""

?

TIA
