I believe there is often a bug in such code. If you want that we hide these bugs by removing the casts I can do it.. but I personally think that is wrong. And yes clang-tidy does not have static analysis. that would not help much to determine proper fix anyway - if we can see there is overflow then should it be fixed with fix 1,2,3 or is the overflow intentional.
