Hi Nicola 

it has been a while since my last FOSDEM :)

Well what I am trying to achieve, is just what I wrote (why doesn't anyone seem 
to believe me :)). I want to lookup an implementation as fast as possible and 
note if it is forwarding or not at the same time. If I have to do it in two 
steps, it's just going to be a bit slower. But I'll probably have to do that.

It's an optimization thingy, as you might have guessed.

Ciao
   Nat!
