I think we're now on the same page on most of this, but there is one point we're not.

Also what is the reason that you're afraid of using unless?
I strongly dislike the action appearing before the condition. I find it to be a lot more prone to causing confusion (for me) and decreasing readability. (And yes I know there's plenty of people who argue it does exactly the opposite.)
This isn't what I was talking about. I asking about writing 
    if (! defined $self->{_condition}{$condition}) {
      $self->{_condition}{$condition} = Condition->new();
    }

versus 
    unless (defined $self->{_condition}{$condition}) {
      $self->{_condition}{$condition} = Condition->new();
    }

There are arguments both ways, I was wondering what your arguments were. (Basically my belief is that if you're going to offer advice, you should be able to back it up.)
