I am trying to create a hash and then print it out. When executing program, I am getting $key & $value need explicit package. O wise monks, please show me the error of my ways :) 

#! /usr/bin/perl
use v5.12;
use warnings;

## 2/15/19

     my @people = qw{ fred barney fred wlima dino barney fred pebbles 
+};
     my %count;    # new empty hash
     $count{$_}++ foreach @people;

     while ( ($key, $value) = each %count) {
       print "$key => $value\n";
    }
