You don't really need a linter. It's just a warning setting, see: -Wimplicit-fallthrough From the compiler docs. It's just not a problem. If you waste time once and learn about warning options in the compiler you will be better off anyway. It's like with assignment being an expression panic - something that maybe bites you once and then you learn to read the compiler warnings and it never causes problems again. If you don't want to read then there is: -Werror Available.
