The refusal to use anything language designers have learnt since 1970 is what makes it C. No sum types, poor error handling, no map/filter funcs, all the other stuff written in the post. Java has all of that, any language after the 90s has most of that, Go doesn't. Actually even C has sum types lol.

The fact that it can't fill many of the usecases that C can and yet has ergonomics as bad as C makes it even worse.
