Unable to use underscore in identifier

[MarkintoshZ]

I wonder why using the underscore character in identifiers is not allowed here.

debug_function: func()

gives the following error

invalid character in identifier '_'
     --> input:1:1
      |
    1 | debug_function: func()
      | ^

Also, where could I find the formal definition for .wit files?

When wit-bindgen generates bindings for high-level source languages, it follows their naming conventions, such as using camelCase for JavaScript and snake_case for Rust, and so on. To be able to do this, it needs to be able to identify where the word separators are, so wit restricts the format to kebab-case.

There is not yet a formal definition for wit, though discussions have started about setting up a standards home for it.

Thank you. That makes sense.

For now, you can reference the WIT.md file in this repo
