no wasm. just rust.

Steps to Reproduce

  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

Actual Results
