In older versions of Clang, 4 errors are displayed: ```{{call to deleted constructor of{{.*}}}}```, but in new version is 6 errors. So when I have added ```{{call to deleted constructor of 'MoveOnly'}}``` It takes one of the error ```{{call to deleted constructor of{{.*}}}}```, that's why I needed to add 0-1 here
