Why is a preprocessor bad? I do tons of platform level programming. Let’s say I’m doing Metal. There is #if ISO, #if APPLETV, #if MACOS stuff around the code. Sure, I could over engineer by trying to pass in some specialization functions but it can get extremely tedious and ugly to deal with. There’s a time and place for both. If I recall correctly, C# didn’t ship with one but it was added. For one it makes it easier to use the standard build system (just compile all the files referenced) rather than have to use an outside build system that knows when to include linux.xxx and when to incluide windows.xxx etc. Of course I’m aware of some of the drawbacks but I’d prefer with than without.
