Topic: Wit function name using _

Hi, is there a way to define wit function names using snake case? I tried to use the " or the % prefix but every time when I try to generate the bindings with the wit-bindgen rust-wasm I get the invalid character in identifier error.

Identifiers in wit are required to be kabob-case; this lets wit-bindgen map them to CamelCase or snake_case to match the conventions of different source languages.

you should as a result see idiomatic identifiers in all languages, e.g. snake-cased in Rust, camel-cased in JS, etc
