    Fixed, but it doesn't work as I need :-( How can I access from the script to the hash %some_words created in the module?

      If you like to export all into the callers namespace put 
      @EXPORT      = qw (loadwords %some_words);

      into your module code. But this is not a good idea. what about returning a reference to the new created %somewords? 
      sub loadwords {
    my @words = qw(a able about above across actually after again all)
+;
    my %some_words;
    foreach (@words) { $some_words{$_} = "1"; }
    return \%some_words;
}

        I like this solution. I think I'm gonna use references to the hash.

        Thank you everybody.
