[phobos] Fw: cast(bool) vs. opUnary!"!"

[Steve Schveighoffer]

The only thing it disallows is making !x return something other than a bool.  The only place I can think of that would be useful is some sort of logic type that has more than 2 states, but that's a stretch.

The current implementation looks good to me, I was just curious about it.
