Test Case

TODO: upload Wasm file here
no wasm. just rust.

Steps to Reproduce

• TODO: first, ...
• TODO: second, ...
• Etc...
• crate a new cargo project
• add wasmtime with the component-model feature
• use the below wit in the wit/ folder with bindgen!()
• see error

package jcbhmr:hello-world-rust-wasm-component-lib;

interface my-box {
  resource my-box {
    constructor(value: u32);
    value: func() -> u32;
  }
  set-global: func(value: my-box);
  global-value: func() -> u32;
}

world example {
  export my-box;
}

Expected Results

it to either auto-rename it due to duplication or otherwise scope it so that this collision doesn't happen
