One may not know the minimum & maximum values without inspecting to use range operator, so ... 

use strict; use warnings;

use List::MoreUtils 'minmax';

my %hash = ( ... );

#  Absurdity is to find end values in order to avoid
#  numeric comparison.
my ( $min , $max ) = minmax keys %hash;

for my $i ( $min .. $max )
{
  ...
}
