Hello, I'm curious to learn more about Kotlin/Wasm and the potential for supporting the target in my KMP libraries. Is there support for interop with native Wasm libraries? I currently use Java, Objective-C, and C SDKs in one of my libraries. If the C SDK were to be compiled for Wasm, would I be able to use it from Kotlin?

Hi, yes, you can do that but only for top level functions with primitives for parameters types and return value type, like `i32` ,  `i64` ,  `f32` ,  `f64` , etc. To import such function directly (i.e. without passing the execution through the JS) from side module into the Kotlin one can use `WasmImport` annotation. Something like:
```@kotlin.wasm.WasmImport("importModule", "importFunction")
external fun foo(a: Int, b: Float): Double```

Great, so there's limited support currently. Will there be support similar to C and Objective-C interop in the future?
