Re^2: Surely @a is local to sub load?

Don't do that. As you mentioned, my @a unless @n; is officially undefined behaviour. Instead, use

{
    my @a;

    sub load {
        push @a, @n;
        @a
    }
}
[download]

use feature qw( state );

sub load {
    state $a = [];
    push @$a, @n;
    @$a
}
[download]
