Comment:

 I am inclined to leave it as is. Double negation is rather popular pattern
 and in majority of the cases does the right thing. I guess there is
 something special about your  operator!, but you can always cast to bool
 explicitly.

 So, unless if you can come up with the way to continue support types with
 only operator! implemented (using enable_if or something) we probably
 should keep it as is.
