in reply to Iterating through referenced arrays wihthin a hash

Use CPAN. Specifically, the natatime() function in List::MoreUtils. 
my @arr = (
    [ 0 .. 3 ],
    [ 4 .. 5 ],
    [ 6 .. 9 ],
);

my @all = map { @$_ } @arr;
my $iterator = natatime @all, 2;
@arr = ();
while ( my @v = $iterator->() ) {
    push @arr, \@v;
}

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
