Moose/CMOP doesn't make this distinction (since it's rarely necessary,
and would just complicate things). I think doing this setup in BUILD
would probably be the cleanest/easiest way, but you could probably
fiddle something into working with initializer (from
Class::MOP::Attribute) if you tried a bit. Trigger probably won't help,
since it's called both during construction and when setting.
