if you need more than a simple statement use do { BLOCK }.

update

NB: the comment alone is no problem, cause it's ignored while parsing and not part of any statement

lanx@nc10-ubuntu:~$ perl -c
sub my_filter {
   my ($hash) = @_;
   return [
      sort {$b <=> $a} keys %{$hash}         #Reverse sort
   ];
}
- syntax OK
