I can't read that. I see a bunch of calls and casts. !() was a little 
hard at first, but this is impossible.

Of course, this is just my opinion, I don't know what the others think 
about it...

Another problem, from an IDE perspective: "Positive." will trigger 
autocomplete of Positive's members, ugh.
