You are correct that this is not working. I think that can be fixed
since the names came from $@.
However, the following is a work around that should work and will
only bind named to the caller.
===================cut here================================
function copy_args # dest src ...
{
nameref newarr=$1
shift
while [[ $1 ]]
do nameref arr=$1
newarr+=(${arr[@]})
typeset +n arr
shift
done
}
newarr=(1 2 3 4)
testarr=(1 2 3 4)
copy_args a newarr
print ${a[@]}
===================cut here================================
