    23  It's named and used in the model of [GNU's seq][].
    24  
    25  ```
    26  3 → 1, 2, 3
    27  1 2 4 → 1, 3
    28  -3 → -1, -2, -3
    29  1 4 → 1, 2, 3, 4
    30  1 -2 → 1, 0, -1, -2
    31  ```
    32  
    33  ## Example: `seq` with `range` and `after`
    34  
    35  You can use `seq` in combination with `range` and `after`. The following will return 19 elements:
    36  
    37  ```
    38  {{ range after 1 (seq 20)}}
    39  {{ end }}
    40  ```
    41  
    42  However, when ranging with an index, the following may be less confusing in that `$indexStartingAt1` and `$num` will return `1,2,3 ... 20`:
    43  
    44  ```
    45  {{ range $index, $num := (seq 20) }}
    46  $indexStartingAt1 := (add $index 1)
    47  {{ end }}
    48  ```
