Why don't you just remove the prototype?

use v5.12.0;
use warnings;

package Somename;
use Data::Dump qw/pp dd/;


foo(1,2,3,4,5);

sub foo {
    my $one = shift;
    my $two = shift;
    my $three = shift;
    my $four = shift;
    my $five = shift;

    pp $four,$five;
}

FWIW: your old code produced a warning that you apparently ignored in the past°

Somename::foo() called too early to check prototype at d:/Perl/pm/foo_prototype.pl line 8.

removing the protoytpe will help you getting rid of this too.
