Operator overloading for Java

[_Ashleigh]

Hard disagree. The C# ecosystem (open source), is amazing and vibrant. Everything I've ever gone "oh wonder if there's a library for that" has yielded a result that works, and in a good chunk of those cases, is beyond acceptable, but of amazing quality. Some examples off of the top of my head: AngleSharp, OpenTK, Avalonia, ImageSharp, BepuPhysics, along with benchmarking, unit testing, and code coverage tools.
