[Omaha.pm] My first hash slice

[<jay@jays.net>]

Huh. I think I just coded my first hash slice in the wild (the 'my $key ='
line). I blame Andy Lester for posting array slices last year.

Is this code evil?

   while (my $href = $sth->fetchrow_hashref) {
      foreach my $key (keys %$href) {
         $href->{$key} =~ s/\s+$//;
      }
      $DB::single = 1;
      my $key = join "|", @$href{ qw(rate_cat room_code hrms_room_cat stod
etod) };
      print "$key\n";
      unless ($self->_Band2s->{$key}) {
         my $b2 = Omni2::Control::OmniCRS::HRMS::Band2->new($href);
         $self->_Band2s->{$key} = $b2;
      }
   }

In the debugger, below...

Ponder,
