(typed) function references

[gkgoat1]

Feature request

Optionally typed function references, which are another kind of reference type.

Why?

I am creating an IDL using this crate for Rust bindings, and want to have a function type

Alternatives

I could implement function reference patching myself, but it would be hard to integrate into the system by this crate.

Hi! Terribly sorry for a delayed response. Do I understand correctly that you mean this proposal, rather than simple funcref? If so, I'd agree that it's nice thing to have; there could be issues with support of this feature in the ecosystem. E.g., walrus (the library used to parse / transform WASM in the crate) doesn't seem to support it.

At least some support for funcref was added to walrus couple of month ago wasm-bindgen/walrus#266
