Assemblyscript: 使用匿名函数时 wasm-validator 错误

这是我的最小示例：当我按照此处的说明 (https://docs.assemblyscript.org/quick-start) 进行干净安装和干净目录并将其用作我的 index.ts 时，出现编译器错误
索引.ts：

// The entry file of your WebAssembly module.
<strong i="7">@unmanaged</strong>
export class Foo {
  use_anon_function(fn: (value: i32) => i32): Array<i32> {
    return new Array<i32>();
  }
}

export function anon_test(bars: Foo, value: i32): i32 {
    let bar_ids = bars.use_anon_function((bar: i32) =>
      value
    );

    return bar_ids.length;
}

npm run asbuild输出：

> @ asbuild /Users/duncanuszkay/src/github.com/Shopify/temp-delete
> npm run asbuild:untouched && npm run asbuild:optimized

如果我不在 anon 函数中使用函数参数，它会编译：
索引.ts

// The entry file of your WebAssembly module.
<strong i="16">@unmanaged</strong>
export class Foo {
  use_anon_function(fn: (value: i32) => i32): Array<i32> {
    return new Array<i32>();
  }
}

export function anon_test(bars: Foo, value: i32): i32 {
    let bar_ids = bars.use_anon_function((bar: i32) =>
      100
    );

    return bar_ids.length;
}

看起来我不能在匿名函数中使用函数参数？ 不过，给出的错误消息似乎并不相关。

如果您需要更多信息，请告诉我
