Examples?

Sounds like redundant complication of ES standard. Could you provide some examples or repo for the problematics? Because the problem seems farfetched.

In their latest release, Bun decided to use an import attribute to interact with sqlite database:

import db from './my.db' with {type: "sqlite"};

const {id} = db
  .query("SELECT id FROM users LIMIT 1")
  .get();

console.log(id); // 1

check support sample.

  async function enableWithTypeSyntax([type, dataUrl, ok]) {
    let enableWithTypeSyntax = false;
    const option = (() => {
      const option = {};
      const w = {type};
      Reflect.defineProperty(option, "with", {
        get: () => (enableWithTypeSyntax=true,w),
      });
      return option;
    })();
    let result;
    try {
      const importMethod = new Function("dataUrl", "option", "return import(dataUrl, option);");
      result = await importMethod(dataUrl, option);
      if (!enableWithTypeSyntax) return [false, new Error("not with read.")];
      const isValid = typeof ok === "function" ? ok(result?.["default"], result) : !!ok;
      if (!isValid) return [false, new Error("type is invalid", {cause: {default: result?.default, module: result}})];
      return [true,"ok"];
    }catch(e){
      if (e instanceof SyntaxError) return [false, new Error("not supported. import attribute syntax", {cause:e})]
      return [false, e];
    }
  }
