Obviously I'm being terse for argument. You can easily imagine InvokeWithErrorLogger(fn, fnparam, log) or InvokeWithErrorAnnotator(fn, fnparam, annotato

  Perhaps something like this? result := InvokeWithErrorLogger( func (err error) { // Error handler incrementMetric("foo") log.Error("bar") }, addTwoNumbers, a, b, ) But the problem is that this approach is not better than just writing this, which doesn't need any new fancy addition to the language: result, err := addTwoNumbers(a, b) if err != nil { incrementMetric("foo") log.Error("bar") return fmt.Errorf("addTwoNumbers(%d, %d) = %v", a, b, err) } Hence why all the proposals ended up dying with the lack of traction.
