On the microsoft c# docs website, it says you can use [^index] to index from the end of an array in c# 8.0 and later, well, I’m in c# 8.0, but it doesn’t work. I’m wondering if it’s possible to make it work by updating Unity, or if there’s some other solution. I’d also just like to know why this doesn’t work, even if there’s no solution.
C# 8.0 seems to be supported with Unity 2020.2 (currently in beta)
Unity 2018.3 → 2020.1 support # 7.3
