They do similar, but different, things. The \ operator takes a
reference to a variable and [] operator creates an anonymous array.
You can build [] from \ by using a temporary array that goes out of
scope.
my $linked = [EMAIL PROTECTED];
my $independent = do { #this is functionally the same as my
$independent = [EMAIL PROTECTED];
my @temp = @array;
[EMAIL PROTECTED];
}
Changes to @$linked will change @array, but changes to @$independent
will not.
