<pre>You need to define operator!() for VMutex, as shown in the documentation. The
expression in the attribute is parsed just like an ordinary C++ expression, so
the operator needs to be available for negative capabilities to work. The
implementation doesn't matter, you can just use
const VMutex& operator!() const { return *this; }
as member function or
const VMutex& operator!(const VMutex& mutex) { return mutex; }
as standalone function. I guess you can actually omit the implementation but I
didn't try if that links.</pre>
