the strange thing is that, in theory, we’re consuming entierly the Enumerator because or code looks like that:

```
  def time_segments(earliest_start, latest_end)
    to_biz(earliest_start, latest_end) // This line creates the “biz" `Linear` thing 
      .periods
      .after(earliest_start)
      .timeline
      .until(latest_end)
      .to_a // here we’re consumming entierly the Enumerator, no ?
  end
```
