using would let us combine the functions into one.

I think we could do one of:

1. Chalk-like

tempPath = String(tempPath)

Object.defineProperty(tempPath, Symbol.dispose, {
  value: () => {
    del(tempPath)
  },
  configurable: false,
  writable: false,
  enumerable: false,
});

2. Return an object

const result = {
    path: tempPath
};

Object.defineProperty(result, Symbol.dispose, {
  value: () => {
    del(tempPath)
  },
  configurable: false,
  writable: false,
  enumerable: false,
});

Definitely object (2).

Maybe also a manual dispose() method on the object, in cases where using using is not convenient.

I would wait until we can use asyncDispose too though. Node.js 24.
