If you have so many accessible properties that you need to generate accessors for them, you may need to re-think your design.

I'm working on a configuration module, so accessors and data are the primary purpose of the module. You can see some background in Configuration Best Practices for Web Apps.

Even if you don't have many, though, I would argue the good kind of Laziness should drive you to use tools to avoid cut and paste. Even with just a few accessors, the code often ends up being largely cut and pasted, so using a module to automate the process is still a nice idea.

    After playing around in several directions, I realized that it's trivially easy to generate default accessors, which may be why there are so many modules for it (although it makes me wonder why there are any).
    for my $property (qw(several members defined public)) { no strict 'refs'; *{"get_$property"} = sub { (shift)->{$property} }; *{"set_$property"} = sub { (shift)->{$property} = $_[0] }; }

    Caution: Contents may have been coded under pressure.
      You got it. I took at look and that's almost exactly what Class::Accessor does.
