 So, how would I know where one variable ends and the next one starts?

 Given that this can be trivally written as shell loop, I don't see the
 point.

 Same here. E.g.:
 
 pkg_info -e '*' | while read pkg; do
 	case $(pkg_info -Q automatic "$pkg") in
 	[yY][eE][sS])
 	        echo "$pkg"
 	esac
 done

 Same problem as the first, can be written as in the former example.
