Kotlin Multiplatform

The real hard part of this is taking the GC side of Kotlin and making that work on these native platforms. And so there's a bunch of work that has to happen underneath the covers for this to all work seamlessly. The new memory model is they call it just became the default in 1.7, I think, or maybe 1.7.20. So yeah, there's been a lot of investment from JetBrands and some from Google now into the optimizations that are happening in the covers here.
