If you want more clarification, see the relevant documentation.

You could try and do some things for illustration purposes:

#!perl -lw # -l appends a \n to each print, -w enables warnings
use strict;
my $aryref = [1 .. 5];
print for $aryref;    # Prints the stringified reference - not what you want
print for @$aryref;   # Dereferencing it lets you access the array
my @ary = $aryref;    # Probably not what you want
print for @ary;       # Stringified reference again
print for @{$ary[0]}; # Dereference the first array element (which holds the ref)
