Discussion on: 13 reasons why you should not use Perl

Regarding point 4, why are you using that syntax? With recent (at least 10 years old I think) versions of Perl you can just do:

sub func1($x, $y, $z) {
    // do something with the variables
}
func1(1, 2, 3);

If for some reason you need to use a very old Perl interpreter, there's still a better solution:

sub func1 {
    my ($x, $y, $z) = @_;
    // do something with the variables
}
func1(1, 2, 3);
