    /// Implementation class for a class per-instance member function with three
    /// parameters.  Each parameter is copied by value - use ::Loki::ByRef if you
    /// must use a reference instead.  ScopeGuard ignores any value returned
    /// from the call within the Execute function.
    ///
    /// This class has 3 standalone helper functions which create a ScopeGuard.
    /// One is MakeObjGuard, which is deprecated but provided for older code.
    /// The other two are MakeGuard overloads, one which takes a pointer to an
    /// object, and the other which takes a reference.
