Panicking, but with style

defer errutil.Auto() // put this once at the top of main()

// to get panics like this:
  panic: runtime error: invalid memory address or nil pointer dereference

  1. main.main()
     /app/main.go:37
          35  func main() {
          36    defer errutil.Auto()
     >>   37    serve()
          38  }

  2. main.serve
     /app/main.go:9
           7  func serve() {
           8    h := &handler{}
     >>    9    h.handleRequest()
          10  }

  3. main.(*handler).handleRequest
     /app/main.go:15
          13  
          14  func (h *handler) handleRequest() {
     >>   15    h.authMiddleware(func() { h.dbQuery("42") })
          16  }

  4. main.(*handler).authMiddleware
     /app/main.go:19
          17  
          18  func (h *handler) authMiddleware(next func()) {
     >>   19    token := h.extractToken()
          20    if token == "" {

  5. main.(*handler).extractToken
