Another solution using List::MoreUtils:

#!/usr/bin/env perl

use strict;
use warnings;
use List::MoreUtils qw(natatime);
use Data::Dump;

my %HoPwy = (
    foo => [qw(abe lincoln  john doe  freddy mac)],
    bar => [qw(homer simpson  krazy kat)],
);

for my $pwy ( sort keys %HoPwy ) {
    # my $pwy_arrayref = $HoPwy{$pwy}; 
    # my $iterator = natatime 2, @$pwy_arrayref; 
    my $iterator = natatime 2, @{ $HoPwy{$pwy} }; 
    while ( my @pairs = $iterator->() ) {
        dd $pwy, \@pairs;
    }
}

__END__
