personally, that's what i would do.
dealing with arrays usually makes the code a
lot cleaner and easier to follow than using
awkward constructs like ${$C_Last}{$i}
and besides, if you ever wanted to expand your
code, you could easily pass the entire array
to a function like so: children( $C_Last );
if you used individual variables, you could
not do that in any easy or efficient way.
