Caller information attributes (``++CallerFilePathAttribute++``, ``++CallerLineNumberAttribute++``, and ``++CallerMemberNameAttribute++``) provide a way to get information about the caller of a method through optional parameters. But they only work right if their values aren't provided explicitly. So if you define a method with caller info attributes in the middle of the parameter list, you put your callers in a bad position: they are forced to use named arguments if they want to use the method properly.
