[Kde-pim] use of std::swap in gpgme++

[Aaron J. Seigo]

hi...

looking at gpgme++ today i noticed code like this:

    const VerificationResult & operator=( VerificationResult other ) {
·       swap( other );
·       return *this;
    }

    void swap( VerificationResult & other ) {
·       Result::swap( other );
·       using std::swap;
·       swap( this->d, other.d );
    }

is swapping d pointers on assignment intentional? it seems a bit odd that 
assigning an object to another results in them swapping their data. (as 
opposed to assigning the rhs to the lhs)
