Hello hlc, and welcome to the Monastery!

This is one case where prototypes are actually useful. From perlsub#Prototypes:

As the last character of a prototype, or just before a semicolon, a @ or a %, you can use _ in place of $: if this argument is not provided, $_ will be used instead.

Hence:

#! perl
use strict;
use warnings;

sub say (_)          # <-- ADD THIS
{
    print @_, "\n";
}

my @a = qw(1 2 3);

say for @a;

Hope that helps,
