feature request: wrapping multiple errors

[wreulicke]

This is a feature request for wrapping multiple errors.

go 1.20 supports wrapping multiple errors. https://tip.golang.org/doc/go1.20#errors

But, failure is a lack of support for wrapping multiple errors.

I want support for wrapping multiple errors.

But, I found you are working on v2. Would you happen to have any plan for support for wrapping multiple errors on v2?

workaround and expected

I wrote current workaround and expected codes below.

err := doSomething(id)
if err != nil {
  // Currently, we have to combine `failure.Wrap and fmt.Errorf`
  return failure.Wrap(fmt.Errorf("foo bar :%w :%w", err, &MyError{
    ID: id
  }))

  // expected like this
  return failure.Wrap(err, failure.Message("foo bar"), failure.WithCause(&MyError{
    ID: id
  }))
}
