   5     |     ^^^^^^^^^^^^^^^^ `Dummy` cannot be formatted using `{:?}`

   7     = help: the trait `Debug` is not implemented for `Dummy`
   8     = note: add `#[derive(Debug)]` to `Dummy` or manually `impl Debug for Dummy`
   9     = note: this error originates in the macro `$crate::format_args_nl` which comes from the expansion of the macro `dbg` (in Nightly builds, run with -Z macro-backtrace for more info)
  10 help: consider annotating `Dummy` with `#[derive(Debug)]`
