What's wrong? I found out, if you define %count outside the foreach loop with my %count; and omit "my" within the loop, it's working. But "my" within the loop results in the mentioned warning.
Nothing! That's exactly how you do it 
#!/usr/bin/perl
use warnings;
use strict;
chomp(my @words = <STDIN>);
my %count;
foreach my $word (@words) {
   $count{$word} += 1;
}
foreach my $key (sort keys %count) {
   print "$key was found $count{$key} times\n";
}
