Shenandoah in OpenJDK 17: Sub-millisecond GC pauses

Not only the GC, since version 7, most of the Midori stuff has been landing on C# (and to some extent F#), turning into a kind of "Managed C++".

Contrary to the WebAssembly speech, CLR was one of the very first VMs to have support for C like languages, but those capabilities were only fully surfaced to the original Managed C++ (.NET 1.0) and C++/CLI (2.0 onwards).

So now those capabilities are being exposed into C# as well.

For example stack allocation of arrays is now also valid in safe contexts.

You can apply using to any type that has Dispose() without inheriting from IDispose.

Memory slices are now also a thing and native function pointers for example.

Last I saw, this was still being debated by the LDT and weighed against similar proposals such as introducing a `defer` keyword like Swift/Go.

You can use it today on C# 9.

Can you link to any documentation/examples?
