Not at all, but I only verified the tests to run on all platforms. I have not checked interoperability with other languages. Verifying the tests pass is just to make sure my lib can be used on these platforms if anybody wanted to use them.

ok. If you ever want to see the state of the art (IMHO) i recommend you to look at wasmbindgen and uniffi in rust. The code generated for the consumer side of the library is absolutely insane. It makes it completely transparent, even when exposing nasty async await functions.
