By that, I mean, not including the usual suspects, such as C, C++, Rust and Go (I know the controversy about the last one being a systems programming language or not).

I'm asking this because I used C for both application programming and systems programming, early in my career, before I moved to using other languages such as Java and Python.

And of late, I've been wanting to get back to doing some systems programming, but preferably in a more modern language (than C) which is meant for that.
