    # array with '[]' ({} for hashes)

# Now the hash stores something like
# this: ("colors", ARRAY(0x...),
#        "numbers", ARRAY(0x...))

# And you can access these arrays with:
print qq(@{$superHash{"colors"}}\n);

# To print an element:
print qq(${$superHash{"numbers"}}[0]\n);
print $superHash{"colors"} -> [0], "\n";

# Size of array:
