WasmGC support?
Firefox and Chrome recently added support for [WasmGC](https://developer.chrome.com/blog/wasmgc/), which allows garbage collected languages to be used with WASM. [Kotlin](https://kotlinlang.org/docs/wasm-overview.html) and [Dart](https://docs.flutter.dev/platform-integration/web/wasm) are two of the first languages to add support to their compilers. Is it possible to use them with WASM4?
