Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/70326 See D24145988 for context: it allows loops such as for(int i=0;i<10;i++) to be expressed as for(const auto i : c10::irange(10)). This is nice because it auto-types the loops and adds const-safety to the iteration variable.
