This code cuts out two keys/values... Any ideas?
use strict;
my $names = " John 20, Bill 34, Jane 28, Wall 18, Tom 19";
print $names,"\n";
my %hash_list = sort(split (/,/, $names));
print %hash_list,"\n";
my @keys = sort {
$hash_list{$a} cmp $hash_list{$b}
} keys %hash_list;
print %hash_list, "\n";
print @keys, "\n";
