  The normal (i.e. Perlish elegant) way to deal with references is to
use a dollar$variable that you dereference later when needed.  (I also
find that Hungarian notation helps programmers and maintainers immensely
with this sort of thing.)

# @ara is an Array of References to Arrays
my $ra = shift @ara;
# $ra is a Reference to an Array
# Now access $ra->[0], $ra->[1], etc.
