No, because it's not basic. You should be using a multi-dimensional
structure, as Lists User recommended. Rather than storing the name of
an array, store the name of a key to your hash of arrays, and let the
value be a reference to an anonymous array.
my %array_named;
$array_named{foo} = [ 1, 2, 3, 4];
$array_named{bar} = [qw/ alpha beta gamma delta/];
for my $name (keys %array_named) {
print "$name: @{$array_named{$name}}\n";
}
