Array References
``` my $names_ref = \@names; ```
``` print $names_ref; # ARRAY(0x703dcf2) ```
``` @$names_ref ```
but it will be probably more readable to write
``` @{$names_ref} ```
or even
``` @{ $names_ref } ```
Once we know all this we can pass a reference to a function, within the function we can dereference the array and we get back the original array.
