Package namespaces and package names are not generatable in combination

[cleanerx]

Looking at the wit-syntax the following is supported

package-decl ::= 'package' ( id ':' )+ id ( '/' id )* ('@' valid-semver)? ';'

Using it

package com:mydomain/tree/leaf;

interface foo {

record stat {
  ino: u64,
  size: u64,
}

}

world x {
export foo;
}

Generating fails with
tool@6fddbba60b7a:/workspaces/test_wit# wit-bindgen rust my_interface.wit
Error: expected '{', found /
--> my_interface.wit:1:21
|
1 | package com:mydomain/tree/leaf;
| ^

I think this should be supported

Thanks for the report! I'll note that the structure of com:mydomain/tree/leaf is "emoji gated" in the component model at this time meaning it's not fully stable and implemented everywhere. What you're running into is that this is an example of it not being implemented.
