You're right, it isn't. [@user] indeed creates a fresh, independent
copy, while \@user doesn't, as shown by the following code:
#! perl -w
use strict;
my $aref1;
my $aref2;
my @array = (1,2,3,4);
$aref1 = \@array;
$aref2 = [@array];
print "Before\n";
print "aref1 -> @$aref1\n";
print "aref2 -> @$aref2\n";
$array[1] = 'x';
print "After\n";
print "aref1 -> @$aref1\n"; # prints 1 x 3 4
print "aref2 -> @$aref2\n"; # prints 1 2 3 4
