I don't think we could use both.
Here's a code snippet of actually using them

# How baselayout-2 presently handles arrays
eval "$(_get_array array)"
for x in "$@"; do
    echo "$x"
done

# How baselayout-2 may handle arrays based on this discussion
IFS="
"
for x in $(_get_array array); do
    unset IFS
    echo "$x"
done

Assume that the _get_array function correctly maps the bash array to the
posix shell one in both cases.

Thanks
