Comment (by anonymous):

 Actually the boost classes don't need `swap` methods of their own, they
 can just use the ones inherited from std:
 {{{
 class myifstream : public boost::filesystem::ifstream {
         myifstream() { }
         myifstream(myifstream&& other) {
                 swap(other);
         }
         myifstream& operator=(myifstream&& other) {
                 swap(other);
                 return *this;
         }
 };
 }}}
 {{{
 auto f3 = StreamOpen<myifstream>("filename", std::ios::binary); //
 succeeds
 }}}
