Question about Error.prepareStackTrace

[theratliter theratliter]

Hi all! I have a question about `Error.prepareStackTrace`.  I want to collect all stacks of error and do not affect the user. V8 document said `the custom prepareStackTrace function is only called once the stack property of Error object is accessed`.  And the code as follows works. Does this code have any problem ?

```

function test() {

    Error.prepareStackTrace = (error, stack) => {

        /*

          collect the stack here

        */

          return error.stack;

    };

    const error = new Error();

    throw error;

}

test();

```

As the documentation says: this api is just for rendering the stack, not for trapping all exceptions that are thrown.

The closest you can currently get to that is --print-all-exceptions, but that obviously only works locally and just prints the exceptions.
