+Golang is the only language from that list that has full mature support for natural sorting in lots of languages. This code implements sorting in 23 languages. It is also very fast, close to Rust although it is not obvious how to optimize its code to work so fast.  Although Golang has simplified syntax it is not simple to know how to use its full power.
