Good point; however, the way you'd normally dereference an arrayref generates a fatal runtime error:

$ perl -le '           
    my $think_this_is_an_arrayref = \(qw{one two three});
    print qq{Probably not dereference like this: $$think_this_is_an_ar
+rayref};
    print qq{Probably would dereference like this: @$think_this_is_an_
+arrayref};
'
Probably not dereference like this: three
Not an ARRAY reference at -e line 4.
