For reference:
Valid is either
sub () { my ($x, $y, $z) = @_;
sub ($x, $y, $z) {
I should have said
my ($x, $y, $z) = @$_[0];
If $_[0] is an array reference, @$_[0] becomes a list.
The joke was a reference to most wrong Perl programs being valid for something.
Hence the meme: "93% of Paint Splatters are Valid Perl Programs"

Why the empty prototype in the first alternative?
