Walter and I agreed that cast to bool is as good as opUnary. Overloading
unary "!" is now not possible.

Subject: cast(bool) vs. opUnary!"!"
In the latest dmd 2.041, cast!T was added, and if statements were changed to do:
if(s) => if(cast!bool(s))
What happened to if translating to:
if(!!s)
which translates to ! opUnary!("!). Hm... that's a lot of !'s :)
I thought that was the plan, at least it was in the book. Is that going away?
It does make more sense to use cast(bool) because opUnary!"!" could potentially
return a non-bool value.
