How to extend a class in Rust

[xubaiwang]

For example, I need to declare a WebAssembly.CompileError class which extends builtin Error class.

However, I cannot find such API in neither #[boa_class] nor ClassBuilder, is that possible in boa now?

I have found an issue #3314, but it seems to be inactive since two years ago.

Is there any valid workaround now?
