in reply to Foreach syntax

This is untested, but it should work: 
 my @used = grep( %is_available{ $_ } ) keys( %is_available );

 for my $p9 ( @used ) {
      # use $is_available{ $p9 };

    This is untested, but it should work:

    I personally believe that you should test it then, since (we're not under Perl 6 yet and) the %is_available{ $_ } form of subscripting/slicing doesn't exist! Incidentally, I wish it did, but... for something completely different!
